How to setup a completely headless browser with Flash support on your linux server

noreply@blogger.com (Nikolay Matsievsky) — Wed, 03 Apr 2013 13:56:00 +0000

Environment setup

PhantomJS is a beautufil product to launch a headless web browser or your linux server. This can be used to automate a large amounts of tasks which can't be processed with raw curl.

So we have CentOS release 5.7 (Final), 32bit, and need to get completely loaded websites with Flash support. PhantomJS isn't supported Flash plugin since 1.5.0, so we need to use 1.4.1 version. All components can be installed via these guides: rhythmicalmedia.com/?p=146 and code.google.com/p/phantomjs/wiki/XvfbSetup. All should be OK (maybe except the GIT insallation - but phantomjs-1.4.1 is in source code, so no actual usage of GIT).

To start Xvfb you need to add these strings to /etc/init.d/Xvfb

# chkconfig: 345 99 50
# description: Simple graphical server

To make chkconfig work with it. You may need xfvb-run script, one can be obtained from here www.minecraftwiki.net/wiki/Programs_and_Editors/Tectonicus/VPS.

Flash plugin installation routine

rpm -ivh http://linuxdownload.adobe.com/adobe-release/adobe-release-i386-1.0-1.noarch.rpm
rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-adobe-linux
yum check-update
yum -y install flash-plugin nspluginwrapper

Command line must contain option --load-plugins=yes - so the correct ones will be

export LIBXCB_ALLOW_SLOPPY_LOCK=1;DISPLAY=:0 ./phantomjs --load-plugins=yes ../examples/rasterize.js URL SCREENSHOT_FILE

export LIBXCB_ALLOW_SLOPPY_LOCK=1;xvfb-run --server-args="-screen 0, 1024x768x24" ./phantomjs --load-plugins=yes ../examples/rasterize.js URL SCREENSHOT_FILE

Also to emulate Flash support in phantomjs browser you need to add before page.open the following (at least plugins and mimeTypes - to pass all Flash detection tests correctly)

page.onInitialized = function () {
        page.evaluate(function () {
            window.navigator = {
                plugins: {length: 2, 'Shockwave Flash': {name: 'Shockwave Flash', description: 'Shockwave Flash 11.6 r602'}},
                mimeTypes: {length: 2, "application/x-shockwave-flash":
                    {description: "Shockwave Flash", suffixes: "swf", type: "application/x-shockwave-flash", enabledPlugin: {description: "Shockwave Flash 11.6 r602"}}
                },
                appCodeName: "Mozilla",
                appName: "Netscape",
                appVersion: "5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.22 (KHTML, like Gecko) Chrome/25.0.1364.172 Safari/537.22",
                cookieEnabled: true,
                language: "en",
                onLine: true,
                platform: "CentOS 5.7",
                product: "Gecko",
                productSub: "20030107",
                userAgent: "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.22 (KHTML, like Gecko) Chrome/25.0.1364.172 Safari/537.22",
            };
        });
};

If you have any troubles with failed flahs plugin initialization (on screenshots) you may need to downgrade to version 10 by the following command

yum erase flash-plugin
rpm -ivh http://dl.atrpms.net/el5-i386/atrpms/bleeding/flash-plugin-10.2-1.i386.rpm

All this makes headless PhantomJS browser work with modern Flash websites.

v1.6.2 released

noreply@blogger.com (Nikolay Matsievsky) — Wed, 15 Aug 2012 13:15:00 +0000

After long summer vacations we release new version of the best PHP website acceleration software - WEBO Site SpeedUp. Inside the changes:

Added option to restrict HTML scaling by folder. Large website has dozens of thousands of images, and not of them need to be parsed for scaling. So now you can limit HTML images scaling by 1 folder only, this will improve overral website performance for large amount of images.
Added option for AJAX requests caching. By default WEBO Site SpeedUp passes all AJAX requests as they are (without any optimization changes), but now you can add server-side caching for them.
Added spot WEBONOTOPTIMIZE for script exclusion. Now you can exclude some JavaScript code chunks from optimization / moving inside the HTML code by just adding /*WEBONOTOPTIMIZE*/ to them.
Improved data:URI. Minor algorithm improvements for better compatibility.
Minor fixes

You can safely update your WEBO Site SpeedUp installation, or download the latest version from the official website.

v1.6.1 released

noreply@blogger.com (Nikolay Matsievsky) — Tue, 05 Jun 2012 16:35:00 +0000

After the previous version has been released we tuned a few functions and improved overall performance and stability. Also we added some more features to CDN module.

Added option Regular Expression for CDN. Now you can define syntax of your images to be distributed, and all of them will be parsed through generic algorithm and also HTML Sprites will be applied.
Improved performance. Some more functions has been reengineered and product stability has been improved.
Improved Apache modules detection. More powerful way to detect Apache modules and not break website if something is wrong with them.
Improved CDN sync tool. Now RackSpace Cloud is completely supported.
Added DLE module.
Minor fixes.

You can update WEBO Site SpeedUp from product interface or download the latest build from WEBO Software website.

v1.6.0 released

noreply@blogger.com (Nikolay Matsievsky) — Sun, 29 Apr 2012 09:24:00 +0000

New month - new WEBO Site SpeedUp version. We have released all our thoughts about high website speed, fixed minor issues with functionality and performance - and have prepared the next stable version of the best website acceleration solution.

Improved Enhanced mode for unobtrusive loading. A lot of widgets can now be safely loaded on window.onload (including almost all of advertising blocks), also a lot of logical and functionality fixes around unobtrusive loading. There are widgets - DirectAdvert, Teaser.cc, InetLog - added to Unobtrusive loading.
Added option Unobtrusive Configuration. Now you can manage Unobtrusive loading even more easily - you can set sequences of any widgets which need to be loaded first and which can be delayed to window.onload. For example you may show 2-3 banners to your visitors first, and the rest of ads can be moved to onload event. No additional knowledge is required here - just the understanding what do you want from your website - high speed or high revenue, or both :)
Added tool Minify CSS/JavaScript. After several requests from our clients we added one more optimization tool to minify CSS and JavaScript files automatically. This can be dangerous (due to incorrect scripts notation), so please be careful. Minifying engine is taken from website configuration settings (Minify CSS and Minify JavaScript).
Added tab with PHP info to System Status. Now you can check the system features and modules existence easily with generic PHP info block.
Improved performance. Some of the product functions have been simplified / rewritten to reduce time of common operations execution. We are going to minimize impact of the product to the website performance (server-side) with significant improvement in its current performance (both client and server side).
Improved data:URI. New logic has been applied for Regular Expression procedure, also IE7- hack has been modified not to conflict with Google Chrome features.
Improved WEBO Rocket. More stability added and some bugs fixed.
Minor fixes

You can upgrade directly from the product (please be careful if 1.5.1- version is used - you need to upgrade to 1.5.2 first (and then to 1.6.0). You can also download the latest packages from our download page.

v1.5.3 released

noreply@blogger.com (Nikolay Matsievsky) — Fri, 30 Mar 2012 14:56:00 +0000

We are planning major update to the product and even the phylosophy of website acceleration, and the new product version is just a step on this way. We are glad to announce new key functions:

New update mechanics. First of all you need to update to 1.5.2 before updating to 1.5.3 or upper. We changed update procedure logic to keep product integrity on update, and it's not compatible with the old versions.
Added options Rocket CSS, Rocket JavaScript. new options add extreme speed for all CSS and JavaScript files and are available from Zero product edition. They are safe to use, but can shring website load time by 20-40% easily! It acts like a magic - just turn these options on and be glad about faster website w/o any damages to design or functionality.
Added option 'Put styles first'. One more critical for most websites options: styles are being loaded sometimes after scripts, so it's important to put them before automatically with all inline/external files logic and conditional comments. And this is done by the new version of the product.
Improved HTML Sprites / scaling. There are a lot of new logic around HTML sprites and scaling to improve overall product reliability and don't crash on huge projects.
Added currency option. Be default all files in HTML cache are named with current currency (to separate different languages / currency in cache). Now you optimize this option by default currency, this will reduce size of HTML files in cache by 30-50%.
Minor fixes

You can update directly from the product - but please be carefull with 1.5.2-1.5.3 transition. New versions are also available to download from the WEBO Software website.

v1.5.2 released

noreply@blogger.com (Nikolay Matsievsky) — Sat, 03 Mar 2012 22:10:00 +0000

We have taken a good speed in 2012 year to bring new approaches and new quality standards to website performance optimization. With a new WEBO Site SpeedUp version we made one more step for 1-click faster website.

Added Zero Edition. With 1.5.2+ versions there will be no Free (or community) Edition of the product. All editions will be commercial. The first one - Zero Edition - will cost about $25 (lifetime license).
Added welcome letter. After years of customer feedback we have brought together different parts of optimization process and huge amount of user questions in 1 document. Now it's sent right after the installation - to help our users understand website performance better and be more familiar with the product.
Improved caching performance and stability. Large number of issues have been closed, and now caching is operating much more stable and less files are being created.
Added update / install integrity check. We released one more integrity level check - of product update files - but it will be completely aailable since 1.6.0 only.
Updated Google Closure Compiler (to b1741) / YUI Compressor (to 2.4.7) libs.
Added UMI.CMS module.
Shop-Script added to supported systems.
Minor fixes.

WEBO Scout - new life for webo.name

noreply@blogger.com (Nikolay Matsievsky) — Mon, 29 Aug 2011 08:04:00 +0000

Recently we have build into WEBO Pulsar a new analytical tool, and in fact a separate product - WEBO Scout. Now you can monitor not only website load time in a browser in real time, but also receive on a regular basis summary of current performance issues and tips on how to improve the situation.

There was a well-known webo.name service which was used directly for this purpose. Unfortunately, this service is rather out of date, and besides it makes statements based on synthetic tests, often avoiding errors in assessing the possible speedup.

To prevent this WEBO Scout was released. It also operates the real parameters of loading of pages in a real browser (now it's only the Internet Explorer 8) and provide information about current issues of the website performance with high accuracy, as well as it counts the possible time of the pages to open in case of the website speedup. To assess the possible acceleration, we apply our module automatically WEBO Site SpeedUp, thus guaranteeing maximum precision of the result.

All you need to get this information - go to Reports in WEBO Pulsar, enter the name of a site or page you want to check and selecting the desired report type, click Create Report. Usually the report will be prepared for a couple of minutes, and it will be available for permanent linking. You can also enable notification by e-mail about reports' creation.

Report Types:

Simple report. A simple website load time test with the calculation of the possible acceleration - quick basic figures for those who want to a few real KPI about their website. Suitable for regular monitoring of the website rate, for example, before and after work to accelerate or change the design of the website. The cost of this report is minimal and is about $0.1.

Basic Report. This report is a bit more complicated, thre is more technical information here: server response time of 4 points without taking into account network delays, the website load waterfall and ranked tips to increase the speed of the site. This report is suitable for more deep study of the website performance issues and it provides a listing of actions to accelerate the website, and all tips are arranged by priority. The cost of the basic report is about $0.6.

There will be added one more type of reports - Advanced one. It will include all the data from the basic report, and it will contain information how to implement the most appropriate advices to accelerate website, as well as lists of files that are affected by these advices. This type of report will be available in September.

Plans for the nearest future

We have a lot of ideas about how to improve WEBO Scout and share with you that a vast experience that we have in the website audit and speedup. We hope that you will wait for WEBO Scout updates with the same passion as we have.

Here we are with WEBO Scout, and we are welcome to any comments on its functionality, or appearance, or usability. Any of your comments are valuable. And of course, we have traditionally encourage all active members of bonus prepaid.

Together, we make websites faster and more reliable!

v1.4.2 released

noreply@blogger.com (Nikolay Matsievsky) — Wed, 06 Jul 2011 06:31:00 +0000

With new version WEBO Site SpeedUp became even more stable and more efficient:

Added option 'Delete expired cache files'. With this option HTML files' caching can be made even faster - with less files every moment in caching folder. After HTML content has been pushed to browser expired files are deleted. This can be also helpful in Extreme mode (wtih auto cache clean-up).
Added DNS prefetching for multiple hosts. Now multiple hosts' distribution is much less painful than before - all new hosts are being requested before any images' are started to download. A bit more speedup for your website.
Improved files' minify.
Minor fixes.

We are preparing to a major release with new breaking through features - keep on them. You can update your website accelerator or just download new package.

v1.4.1 released

noreply@blogger.com (Nikolay Matsievsky) — Sat, 30 Apr 2011 12:45:00 +0000

With new version of world-wide known PHP best website accelerator - WEBO Site SpeedUp - we have added a lot of features about correct caching and CMS support.

This first is an option 'Separate HTTPS cache'. Now you can have 2 HTML caches - for ordinary and secured connections. This is very helpful for large e-stores with a lot of different pages and different connection options (also for CDN usage).
Added option 'use zlib' for gzipping. This can help in case of mod_deflate absence and buggy PHP buffers support on server-side (i.e. complicated WEBO Site SpeedUp calls).
Added option to enable performance A/B testing. Now you can simply test WEBO Site SpeedUp efficiency with A/B testing feature (available with Extended Edition). All data is sent to Google Analytics.

Web Performance Audit

noreply@blogger.com (Nikolay Matsievsky) — Fri, 29 Apr 2011 11:30:00 +0000

With our new solution for large enterprise companies - WEBO Enterprise SpeedoMeter - we allow corporate customers to gather all available info about client-side performance and overall availability about their websites. This solution had been released last year for internal usage to provide services about client side performance for our clients, now it is available public.

WEBO Enterprise Speedometer consists of 4 major parts. First of all it's page load time counter which is a chunk of client-side code and it gathers statistics about every visitor of the current website. This data is processed to get complete picture about current client-side performance of the given website (based on every visitor perception).

The next part, general website availability, is based on our WEBO Pulsar service, which can test your website uptime and functionality with a lot of options and parameters. With this service we can measure and store all the data about issues with server-side performance and stability. This includes information about any network connection troubles, any HTTP errors, and also about periods with large server response time (which is measured very precisely without network delays).

The next part is a competitive performance analysis. We measure website load time for the given website and its competitors and output comparison charts about actual website place on the market. This is very important is you are going not only be better, but the best player on the market. Because you must now everything about competitors to overcome them!

And the last part is our internal web performance expertise, which is focused on actual website client-side issues and provides advices to resolve them and performance estimations when about these advices follow-up. It seems it is the most useful part of WEBO Enterprise SpeedoMeter for technical specialists.

You can read more info on the WEBO Enteprise SpeedoMeter site or request example report for your company by request to sales@webo.name

In many cases WEBO Site SpeedUp Free Edition is not enough, and you can purchase Standard Edition. This Edition doesn't include product installation and tuning (from WEBO Software engineers) but has 2 weeks of technical support for emergency cases (i.e. website is not available).

Speedup services

All WEBO Software (and its official partners) website speedup services (including Fast Website and Turn-key website speedup) are performed on the base of WEBO Site SpeedUp Extended Edition which is not available for a separate purchase (only through official partners or company services). Extended Edition has the following additional features (in comparison with Standard Edition):

All caching methods' support.

v1.3.2 released

noreply@blogger.com (Nikolay Matsievsky) — Wed, 08 Dec 2010 10:51:00 +0000

It's the last public update for the leading web performance product - WEBO Site SpeedUp - this year. It includes a lot of new features and minor fixes.

Improved gzip. There were tested few new gzip-related patterns and WEBO Site SpeedUp support for missed headers, or firewalls, or improper server side configuration, or anything else was improved.
Added charset option. Now with charset option (it is available in System Status - Parameters) Extreme caching mode ic completely safe, and no charset will be broken. Charset is detected automatically on the first install, and can be manually changed.
Added option to choose between files exclusion or inclusion into CSS Sprites. Very useful option if you have only a few images that must be combined to HTML Sprites, then you can easily add them all instead of adding new and new exclusions.
Added option for load time counter (via GA). With this amazing option you can simply count through Google Analytics how many page views you lost with slow website. To perform this you need only to enable WEBO Site SpeedUp with only this counter for a week, and then perform acceleration (with counter enabled). Difference will be clear. All page load time values are being collected into Events (WEBO Site SpeedUp section), and of course you need Google Analytics counter installed on your website.
Improved SEO compatibility. Now all combined .php and cached fiels are closed via nofollow and robots.txt from search engines indexation.
Improved HTML Sprites.
Improved HTML caching.
Drupal 7.x added to supported systems.
Minor fixes

You can update to the last version from the WEBO Site SpeedUp itself or download it from WEBO Software website.

Website stress testing

noreply@blogger.com (Nikolay Matsievsky) — Thu, 02 Dec 2010 12:47:00 +0000

It is important before Xmas season to know more about your website reliability. And of course the exact number of your customers what can you website serve.

Long time there were no tools to perform such an evaluation (except the direct traffic punch) but now you can analyze your website metrics and perform all necessary actions before it go down due to large amount of your clients. One of the best of such tools is Load Impact. Let's look inside this tool and see how simple can be your website bottlenecks analysis.

Configuring a test

Of course most of features are available even with free website test. But to get the maximum details and perfect result you should register and use any of paid plans (they start from $9 per day or $39 per month, it's really cheap). So the first thing is to setup the test. You can use the only website home page URL to get almost all data about its reliability. But can get a bit more.

With Proxy recorder (under Advanced mode -> Load script generation -> Record session) you can setup a set of requests for your website (with various delays); this will completely emulate your visitors' behavior and can tell you how many simultaneous visits your website can serve.

Proxy recorder can be configured in a few steps (you just need to enable a proxy on a given port inside your browser, Firefox in this case), then start recording and go through the target website (to collect all requests, even dynamic and AJAX ones). Then just stop recording and get all these requests in textarea.

Please be sure that proxy is configured correctly and test proxy settings before starting the test.

Before you finish with test setup you should choose amount of visitors to emulate. For a small website 50 visitors will be quite enough.

If you just want to test website reliability for 500-1000 visitors, you can setup step as 100 (not to overload the system and overhead traffic limit).

In the case if you need exact picture of server down due to high load you need to choose 10-20 visitors in step and get complete picture. But this can take several hours to be completed.

Before you can save the test you need to verify it. Usually it is just a formal procedure to be sure that test is correct.

Running a test

After you have created the proper configuration you can run it. Please be aware of long duration of test performance - it can take up to several hours. After test is completed you will get a lot of different charts about pages and resources performance. Let's consider them more.

The main graphics are user load time and accumulated user time. The first will tell you the delay for users before they get HTML page under current amount of simultaneous users online. The second will tell you how website is working under load, how long its pages are being loaded (totally, server and client side), and where is the limit of its reliability (where time becomes more than 10-15 seconds).

Also you can simply compare how different type of resources are being loaded - to find bottlenecks and to fix them properly. For example you can have relatively fast HTML document, but a lot of expenses on dynamic images generation. Or main expenses will be concentrated in HTML latency only. This will appear only after the test is completed.

Resume

Load Impact is a very easy tool to perform such tests, and simple load tests are completely free. So you can quickly check your website reliability and be sure that you are ready for Xmas shopping season :)

Website Availability Issues

noreply@blogger.com (Nikolay Matsievsky) — Thu, 25 Nov 2010 08:20:00 +0000

Availability of the website is a very unpredictable thing. Sometimes from home (or work) your website is accessible, but your friends can't enter it. Also there can be a situation when sometimes your website up and sometimes down (and you can't even prove this). Or website is being loaded very slowly. Solution in each case can be complicated, but let's consider the basic types of such problems:

Unavailability of a large segment of the network. In this case, users from one network segment can't get access to websites in the other segment (eg, due to routing errors). It's easy enough to install special utilities, but you can't usually perform anything in this case. And the problems of this level (global) typically affect hundreds of thousands of sites, and are being solved them quickly.
You can only sit and wait. And hope that your users are in the same boat (in the same segment), which is your website.
Unavailability of a hoster (small segment of the network). In this case, the problems usually lie on the side of the provider (and therefore can be corrected not so fast). Accurately set the frequency and nature of these problems manually is practically impossible, but it is relatively easy with tools for automatic monitoring.
There is necessary in case of any downtime greater than 10-30 minutes to write to support of your ISP: maybe they do not know that something has fallen off?
Great timeout. In this case, in fact, the site works. And open to all users. But not all users can wait for it :)
It is also possible to check (server timeout with WEBO Pulsar, and the total download time with webpagetest.org. If you page generation time on the website is too large, you should apply any of optimization techniques. Otherwise there will be big losses among target users.
HTTP-error on the site. Quite often it happens that due to heavy load (or service provider hardware failures) website starts with an error (500, 502, 503 or similar). Tracking of such things and in-time moving the website to a safer place is also possible, but this of course requires special attention.
WEBO Pulsar would be the best for this purpose (to track when, what time, and with what frequency). With it all unprepossessing "kitchen" ISP come out and you'll know exactly what is happening with your site.
The failure of the site. Sometimes there are minor incidents with the website (due to hardware failure or hosting provider network configuration change), when the availability of the website is not directly affected, but part of the website functionality is broken. For example, database queries are no longer handled. Or debugging messages have been appeared.
Complete knowledge of such situations can only be possible with direct viewing the website (or its basic functionality check). With WEBO Pulsar, you can check how the presence of a specific text on the page, and its absence. This enables the most timely response to the problem.

v1.3.1 released

noreply@blogger.com (Nikolay Matsievsky) — Thu, 14 Oct 2010 11:47:00 +0000

New version of the best website acceleration software - WEBO Site SpeedUp - is here. Main changes:

Added WEBO Nimblizer (image optimization tool). It is based on PHP5 imagepng function with all filters and compression (including GIF2PNG and BMP2PNG functionality) + PCR tool from bolknote. Performance is great (and it works locally instead of smush.it tool), efficiency is also amazing. Now Image optimization becase even simplier.
Cancelled PHP4 back compatibility. There was a blog post about such a decision. Now WEBO Site SpeedUp can be made easy, lighter, and w/o double code. PHP4 users can use 1.3.0- versions - all of them completely support this environment.
Added CSS Minify option. There were a lot of user complaints about broken styles after data:URI application. Now they can be used w/o CSS Tidy library (and it's an value in CSS Minify option).
Separated unobtrusive widgets configuration. One more global change to make product easier to understand and tune. Now you can use Wiki page and config.unobtrusive.php to create your own solution for unblocking JavaScript.
Added option to exclude GET params from URL hash on caching. This is a useful feature for e-commerce websites which widely use different campaign identifiers for the same content pages. Now these identifiers can be excluded from hash, and the same cache entries will be used.
Added unobtrusive support for Affiz ads, Google Translate widget.
Improved server environment detection.
Improved HTML caching (more stability and performance).
Minor fixes.

You can update to WEBO Site SpeedUp v1.3.1 right now - it is ready!
