Server-side caching engine

noreply@blogger.com (Gleb Kondratenko) — Fri, 02 Jul 2010 22:28:00 +0000

We are happy to announce a brand new server caching engine for WEBO Site SpeedUp.

This caching engine is available for several WEBO Site SpeedUp native plugins like WordPress and CS-Cart and it can be very helpful for many heavily loaded websites.

Here is the brief description.

Formerly, with WEBO Site SpeedUp plugin you could only cache HTML documents on a certain static site sections, or for certain browsers with specific cookies, etc. Now you are able to provide cached pages to almost every user on every page of your website.
Server caching feature is now implemented on a system level. This makes possible for WEBO Site SpeedUp to deliver pages for your website visitors up to 4 times faster than before, and even faster than with many other caching solutions available.
Cache is automatically updated when needed. For example, when someone someone creates a new blog entry or comments it, all related pages are updated in a cache automatically and without your attention.
And of course, along with the new caching feature all familiar WEBO Site SpeedUp features are fully available.

And this is just the beginning. Right now system level server caching already works for WordPress and CS-Cart WEBO Site SpeedUp plugins. But stay tuned, as we are already working on similar solutions for Joomla and some other systems.

WEBO Site SpeedUp supports CS-Cart

noreply@blogger.com (Nikolay Matsievsky) — Fri, 25 Jun 2010 11:33:00 +0000

With new version (1.2.0) WEBO Site SpeedUp completely supports CS-Cart as a native addon for this popular e-commerce solution. This addon has the following useful features:

Complete server side caching for anonymous users (and w/o any items in cart).
Smart cache clean up on product modifications.
Clean interface to access to all products features.
Complete client side acceleration provided with WEBO Site SpeedUp main product.

WEBO Site SpeedUp installation to CS-Cart is very easy. It's described in Wiki (and documentation): code.google.com/p/web-optimizator/wiki/InstallingCSCartPlugin. Also there are a lot of articles about application tuning and configuration.

WEBO Site SpeedUp for CS-Cart shows about 2-2.5x client side acceleration among 4-5x server side speedup (totally 10x speedup), and it is a must-have addon for successful CS-Cart e-stores.

You can check addon discussion on CS-Cart official forum here and here.

v1.2.0 released

noreply@blogger.com (Nikolay Matsievsky) — Mon, 21 Jun 2010 11:02:00 +0000

With a lot of minor compatibility fixes, better CDN support and SaaS Edition new version of WEBO Site SpeedUp was released. What is new:

SaaS Edition. Now all trial keys work in SaaS mode, and you can pay only for enabled features. SaaS Edition is the same in functionality as Premium Edition, but every paid feature has its own price, and overall day outgo is calcualted as simple sum of enabled paid features. Also license prolongation is made simplier: you just need to increase internal application balance via modules codes. This will allow you to use WEBO Site SpeedUp as long as you want for your website. Also you can easily switch optimization cost by selecting active configuration and pay only its price.
Added option 'Extreme mode' for HTML caching. After deep research into website performance we added new feature which allows you to put performance of your website to the new level. With RewriteRules on Apache level you are able to completely eliminate all server side costs and make your website really faster than lightning. This option fits only static (or almost) websites, because all pages are hard cached, and cache reload is possible only as a manual action.
Fixed HTML Sprites placement. Improved internal logic for HTML Sprites images placement, this eliminated a number of known issues with them.
Added separate cache for mobile agents. Now website content for all known mobile agents is separated (as well as it done for IE browsers and the others), and you won't worry about your website compatibility with mobile browsers.
Improved caching for CSS/HTML Sprites. Now all Sprites has unique URLs to force cache reload on their re-creation. Please note: you must disable and enable WEBO Site SpeedUp to make this feature working.
Improved PHP proxy library.
Improved caching / gzip / CDN usage.
Minor fixes.

You can download or update your WEBO Site SpeedUp to get all these new features.

WEBO Software landed in Portland

Most of our site pages are loading in under 2 seconds, compared to the 8 or 9 seconds we started with. This has lead to a substantial increase in the both the average time on site as well as the number of page views. The increased speed has also resulted in a higher conversion rate.

Langocity is a e-commerce website based on Magento that specializes in selling a wide range of foreign language courses and translation software. Their server is located in Portland, Oregon, and receives 30-40,000 visitors from east to west coast every month. Even with mid-level VPS hosting specifically tuned for Magento (which is used as a CMS solution for Langocity) and current CDN (EdgeCast) the site’s load time was too high, resulting in many visitors exiting the site after only several pageviews.

Langocity described the situation, “Even with a well provisioned and tuned server, Magento has a reputation for being somewhat slow, due to the complexity of the shopping cart software. We wanted to improve our pageload times, which were unacceptably slow both for our U.S. customers as well as our customers overseas.”

“In the past, we had implemented a content delivery network on our site, but due to Magento’s complexity, it wasn’t possible to combine all of our JS and CSS files and have them delivered over the CDN without incredibly complex customization. We were concerned with having to support this customization over time, which would be a distraction from the core business. WEBO Site SpeedUp allowed us to fix this issue easily while also optimizing the site in a number of other ways that we hadn’t even considered implementing due to the amount of work it would have required.”

WEBO Site SpeedUp has a numerous number of optimization modules, and almost all of them had to be implemented to completely speedup Langocity, starting from assets merging and finishing with advanced CDN settings for secured connection. Fortunately all of these modules are included into one package with various settings, which makes the website acceleration process very simple and straight forward.

According to Langocity, “One issue that WEBO Site SpeedUp really fixes is an implementation of a wide range of speed optimization techniques that your average developer is not aware of or isn’t too interested in implementing due to the time or effort required for what appears to be a small payoff. For a lot of people, shaving a few milliseconds off page load here or there isn’t worth optimizing. However, when you start applying a wide range of techniques those milliseconds add up to multiple seconds saved, which is very substantial. Since WEBO Site SpeedUp is applying the changes to our site without having to modify our underlying Magento installation, it’s saved a great deal of time and allows our Magento developers to focus on making sure the site runs well, rather than having to spend time implementing very complex page optimization techniques.”

After WEBO Site SpeedUp had been fully implemented, Langocity’s website became about 4x faster. Customers are clearly enjoying the faster site as Langocity has experienced a significantly higher conversion rate and lower bounce rate since WEBO Site SpeedUp has optimized the site.

Website load speed was remarkably increased, and this makes happy both website visitors and editors.

Web portal about health, «Be healthy» (vllv.ru) was launched in spring, 2010. Right after its launch there was decided to speed the website up to make it ready for high traffic and public visitors. This way not only server resources usage should be optimized, but also visitors loyalty increased. Website audience at most consists of megacity residents, and they are accustomed to high website load speed. Therefore there must be applied exceptional measures to increase website quality.

Web portal uses a lot of external widgets (from social networks and Google), so its load speed depends a little from the current CMS (Joomla!) and VPS hosting. To improve the situation there was necessary to use only client side technologies acceleration, and it was the finest hour for WEBO Site SpeedUp.

Unobtrusive JavaScript (delayed loading) modules usage significantly improved current website load speed value (Google Webmasters data showed 2x speedup). And by the web portal management team, “website load speed was remarkably increased, and this makes happy both website visitors and editors.”

You must follow rough technological criteria and quality standards to make website working at maximum. And website load and interaction speed is crucial at this point of view (especially to fit audience expectations). Fast websites not only consume less server resources (CPU and I/O) per visitor, but also provide more comfortable pages surfing and information mining.

WEBO Site SpeedUp, being a complex solution to speed the website up both on server and client sides, allows you to apply tremendous set of technologies easily for your website and combine them on demand. Superior results of application work are proven by thousands of accelerated websites and a lot of satisfied users.

v1.1.3 released

noreply@blogger.com (Nikolay Matsievsky) — Thu, 03 Jun 2010 20:14:00 +0000

More and more features before coming SaaS edition of WEBO Site SpeedUp:

Improved HTML caching engine.

Added option to use HTTPS host with CDN. CDN usage was made completely compatible with all of known CDNs.
Added option to exclude JavaScript files from minify. It's very useful if some JavaScript files are already minified, and additional minify can break them. Now you can safely merge and minify all your JavaScript code.
Added option to include unobtrusive JavaScript loader as inline code. One less HTTP request with unobtrusive logic (with window.onload).
Improved JavaScript merging. Some minor fixes with JavaScript file placement and fix for Shadowbox base URL.
PixelBack and Verisign added to supported widgets.
CS-Cart added to supported systems (by native addon).
Minor fixes.

Healthy speed for website about health, WEBO Software says no smoking

After acceleration we noticed remarkable drop in server load and user session time enlargement.

Health portal "How to stop smoking" (kurenie-yad.org/) appeared in the year 2007. Portal evangelizes healthy lifestyle and smoking cessation, proving for its readers large number of collateral materials. Portal attracts about 60,000 visitors every month, and its load speed significantly influences website quality and its popularity so far.

There are visitors from all over the world on this website. Moreover «How to stop smoking» uses a lot of social widgets (Google Connect, Facebook Connect, etc) to hold audience. This all sets strict requirements to the overall website performance, especially ti its client side. In this case project's VPS hosting plays well and allows us not to implement additional caching layers to speed the website up.
After the first stage of website acceleration (regarding Google Webmasters data) its load speed increased by 30%. Common actions to accelerate the website helped a little, so there was decided to integrate additional WEBO Site SpeedUp modules with delayed social widgets load (Unobtrusive JavaScript). After their implementation website load speed increased almost 3 times (up to 3.1 seconds against 9.1 seconds initially). Vlad Kulikov, project administrator, said that "after acceleration we noticed remarkable drop in server load and user session time enlargement."
High website load speed is required to form a stable users core. In this case the use of embedded communication tools of known social networks only make the client side speed slower, forcing to implement more aggressive methods to change the website load flow, based on the latest research and development in the area.
Website load speed primarily influences the website quality and its ability to target the owner's business goals. Therefore, in conditions of acute competition and the high quality standards it's necessary to implement the most stable, productive and time-tested solution - such as WEBO Site SpeedUp. Practice shows that the acceleration site is worthwhile for a few days, in rare cases a week, but it brings increased profits to the website owner even after a full ROI.

v1.1.2 released

noreply@blogger.com (Nikolay Matsievsky) — Sun, 16 May 2010 18:23:00 +0000

Every day there are more and more fast websites around us. And we are happy to support this trend. So features of the new version of WEBO Site SpeedUp.

Added pre-defined CDNs.

Added 'FTP upload access' option for paid CDN. Few CDN require files to be uploaded manually via FTP (i.e. EdgeCast). Now you can setup FTP access string to upload all assets created by WEBO Site SpeedUp to CDN automatically.
Added 'remove duplicates' option. This option can reduce amount of JavaScript code in case of complicated frameworks usage. I.e. if there are two jQuery libraries, the second one will be automatically excluded from merging. This reduces download time and JavaScript initialization time as well.
Removed check for .htaccess possibility. After various minor troubles with dozens of environments this check is disabled. We are going to re-test this functionality (not to enalbe .htaccess options on unsupported environments and enable them on supported ones) later.
Added cache integrity check. Now all system libs stored in cache directories are re-checked for new versions (to update them as soon as new version is released).
Added exclusion from CSS Sprites images used with AlphaImageLoader. Very helpful feature because you can't apply CSS Sprites for IE if this image is used in filter.
Added webonautes to achievements. Now you can use 5 webonautes to indicate your website acceleration, also achievements page was expanded with total webonautes number.
Magento added to supported systems.
Improved server environment detection.
Minor fixes.

You can update to the latest WEBO Site SpeedUp or download it from the official website.

SWIFT tool for slow websites

noreply@blogger.com (Nikolay Matsievsky) — Tue, 04 May 2010 09:58:00 +0000

noreply@blogger.com (Nikolay Matsievsky) — Thu, 01 Apr 2010 22:43:00 +0000

Few compatibility and performance improvements in the new build of WEBO Site SpeedUp. List of changes:

Page 'Cache' moved to 'System Status' tab (Cache). Now all information about cache files is located on System Status (what is more clear), and there is much less info (because huge blocks of information on the previous Cache page seemed not to be useful). We are working on complete Cache Manager tool (to re-create cache blocks for separate website sections / pages), but it will be a little later.
Excluded 'Performance - Quick check' option. It's misconfigured in the most of cases, and actual performance gain was very little.
Fixed minor compatibility issues. Some more environments now not caused 500 errors on switching between configurations.
Improved minify for CSS files.
Improved client side caching.
Improved UI (minor fixes).

Industry-compliant website speed test

noreply@blogger.com (Nikolay Matsievsky) — Wed, 31 Mar 2010 07:56:00 +0000

Website load speed became significant metric to measure overall website performance and its success (in terma of online marketing efficiency). To help webmasters and managers understand what is the industry standard and how it can be reached we created a scale with website load time and, it's evaluation (in words, not numbers), and possible acceleration grade (with accurate numbers also). All numbers are strictly linked with the current industry standards and you can be sure that after this test is your website slow or not.

You can just enter your website address here: www.webogroup.com/home/test-speed/ and get its speed evaluation. Also there is a link to detailed website load speed test, and a possibility to renew test results.

Website performance awards

noreply@blogger.com (Nikolay Matsievsky) — Mon, 29 Mar 2010 12:37:00 +0000

One of the most prominent feature of new WEBO Site SpeedUp builds is ability to represent current website performance with visual awards. For this purpose we created a rocket which is being improved during website acceleration.

So if you have a slow website, and you have accelerated it - you will be able to share your results with friends, colleagues, and with every your reader or visitor.

There are a lot of words about nothing :), so let's see actual examples.

Rocket examples

If you have tuned WEBO Site SpeedUp to 55 (Options Grade), combined YSlow + Page Speed + WEBO Grade is 95, you have 17 objects per page, and your website has been accelerated by 310%, and its size has been reduced by 10% - you will have this rocket. And then you can share it with everybody, and place everywhere.

This can represent moderate website, which performance has been significantly improved, but w/o hard WEBO Site SpeedUp integration.

The second example - WEBO Site SpeedUp Options Grade is 84, YSlow + Page Speed + WEBO Grade is 65, there are 9 objects per page on your website, its size has been reduced by 70%, and it has been accelerated by 520%.

This website has been accelerated very significantly with a lot of performance features (from WEBO Site SpeedUp) implemented, and with very good trafic savings.

And the last one - you have reached 96 in WEBO Site SpeedUp Options, YSlow + Page Speed + WEBO Grade is 34, there are 4 objects on your website's pages, overall acceleration is 5%, and size reducion is also 5%.

This website hasn't been accelerated much, although WEBO Site SpeedUp was tuned very well. Maybe there a lot of 3rd party widgets, or very limited hosting, and this has lead to such result.

Create your performance award!

There are about 500 different rockets which can cover almost every performance situation with your website. And right now we have 3 different sizes for them - 81x81, 125x125, 250x250 (so there are 1k+ variants). Please share if you have any additional ideas or want some other sizes for your website / blog.

v1.0.3 released

noreply@blogger.com (Nikolay Matsievsky) — Sun, 07 Mar 2010 17:29:00 +0000

A lot of minor usability and accessibility fixes (both in administrative interface and application core logic) is this release. More info:

Added option 'Safe JS combine'. It guarantees that in case of broken JavaScript it will be loaded separately and won't harm other scripts. Here is used try-catch envelope (which reduces a bit performance, so it can be disabled).
Added Basic configuration set. Basic configuration includes all first-priority performance actions, and it is a bit better than Safe one. But it can fail on a few environments.
Added welcome screen after installation. Major UI improvement - now there is welcome screen with quick actions and new features right after WEBO Site SpeedUp installation.
Added Error screen on failed automatic installation. With welcome screen also added Error screen to help understand what is worng (very rarely) with WEBO Site SpeedUp installation (and which actions can be applied).
Other UI fixes and improvements.
CSS Sprites logic improvements.
Improved server environment detection.

HTML Sprites - silver bullet against small images

noreply@blogger.com (Nikolay Matsievsky) — Fri, 26 Feb 2010 19:47:00 +0000

Last builds of WEBO Site SpeedUp include amazing client side optimization approach - CSS Sprites for HTML images. Let's review underneath logic and all related techniques.

CSS Sprites - why HTML?

Actually we are speaking about combining images to a larger one which can be positioned with CSS property background-position. It's impossible to convert raw HTML images to CSS Sprite (to be correct - it's possible but leads a lot of restrictions and drawbacks, i.e. we will have to drop a huge part of images' functionality and properties).

So before any actual operations with images in HTML code (like <img src="..." />) we should prepare them. How? We should convert all images to 'fake' ones - transparent stubs which have initial image as a background, and the same width and height.

Converting HTML images to CSS images

Well. To reduce amount of data (we are going to speed up website, not to increase its load speed) we should choose very efficient approaches to insert transparent stubs. And we have 2 choices:

Insert call to 1x1 transparent GIF image (yeah, bad known spacer.gif which was used a lot several years ago to make table layout). Its size is only 43 bytes (but 1 more HTTP request).
For modern browsers we can use 82-bytes data:URI chunk (which represents this image - data:image/gif;base64,R...Ow==. A bt more data (with gzip usage - about 100 bytes for 1 HTML document, or nothing). But minus 1 HTTP request (cool!).

To provide the best practices here we can combine both approaches - for IE7 and lower use the first one, for all the other browsers - the second one.

Playing with HTML Sprites

It seems now we have all parts for HTML Sprites logic and can reveal it.

First of all - parse initial HTML code to find all images, get their sizes (and skip some large ones).
Then create an array of CSS rules based on given HTML images - just background image (plus no-repeat and zero background position), width and height.
Then just combine all images in 1 CSS Sprite (using existent CSS Sprites logic over current set of CSS rules).
Finally (with a number of CSS classes) replace initial HTML images with stubs with calculated styles.

All this looks very simple. But what are drawbacks?

Troubles and solutions

As far as we need to check size for any image (just to get its dimensions an skip it if it's very large) - we will have a lot of I/O requests with any HTML document. So this can significantly increase server side load time. That's bad. But we can cache calculated dimensions for known images (such dimensions are being changed very rarely) - and skip all future recalculations.

But with every HTML document (with cached calculated dimensions) we have one more expensive CPU operation - CSS background positions calculation (even with completed CSS Sprite we need to get actual positions of given images inside it). But good news here is that we can also cache such calculations (to a set of CSS rules for given HTML image).

Also we must have per-page or per-website modes. Just because you can have thousands of small images through the whole website - but you don't want your visitors to download them all at once.

With all such approaches HTML Sprites technique works both on a high-end servers and weak VDS/shared hosting. And reduces by 20-30% number of HTTP requests for every your web page. That's really amazing. And it's ready to use - just download WEBO Site SpeedUp or update to the latest version.

WEBO Site SpeedUp v1.0.2

noreply@blogger.com (Nikolay Matsievsky) — Thu, 25 Feb 2010 10:57:00 +0000

New version with HTML Sprites support and more performance.

Added HTML Sprites. There are now 3 new options: apply HTML Sprites, dimensions limit for them, and 'per-page' mode (you can combine small images for the whole website, or for the currect page only). HTML Sprites combine small HTML images and replace initial images with transparent one. This can greatly reduce total number of objects on your website.
CSS Sprites refactored. To meet strict resources limit on shared hsoting / VDS core logic for images' placement in CSS Sprites was refactored, and now it consumes much less memory, but a bit more CPU.
Added option 'Days to store cache files'. Now you can restrict number of files in cache with this option (outdated files will be deleted automatically when new ones are being created).
Improved unobtrusive JavaScript. Fixed layout bugs in a few cases and reduced DOM tree size.
Added support for ICO files into CSS Sprites. Now ICO files (as well as JPEG/PNG/BMP/GIF ones) can be combined both to CSS or HTML Sprites.
Improved JavaScript merging for DLE.
Social Engine (3.19) added to supported systems.

WEBO Site SpeedUp v1.0.1

noreply@blogger.com (Nikolay Matsievsky) — Tue, 16 Feb 2010 21:59:00 +0000

We didn't stop with product improvements, and after major 1.0 release continued to make it better. So here is a scheduled 1.0.1 update.

Greatly improved CSS Sprites. There were added a few complicated cases to CSS Sprites logic, fixes memory consumption (approximately by 20-50%). Also improved CSS properties in case of complicated selectors restoration.
Added automated request for 7-day trial key. Now you can test Premium Edition for 7 days (for 1 website) after installation, no performance or feature limits.
Fixed endless redirects on 404 errors. In some cases side caching with wo.static.php lead to recursive redirects. Such situations were fixed.
Added 'Share results on Twitter' buttons. Now you can post your optimization results directly to Twitter.
Minor UI fixes.
Improved static resources caching in case of symlinks usage.
Improved external resources fetching (i.e. in case of dynamic background images).

WEBO Site SpeedUp 1.0 released!

noreply@blogger.com (Nikolay Matsievsky) — Wed, 10 Feb 2010 18:53:00 +0000

After 2 months of creating, tuning, and polishing of the new interface, old and new bugs resolving and general compatibility improving we have released version 1.0 of this outstanding application to speed your website up.

Also we have released our new corporate website (formerly web-optimizer.us) to allow wide range of website acceleration products and services - www.webogroup.com.

Here are few words about new features in 1.0 (in comparison to 0.9.7).

Added option 'Performance -> Restore CSS properties'. It is responsible for correct CSS Sprites creation (parsing CSS rules' tree), but it can be CPU expensive, so it's disabled by default.
