How to test the performance for the code in C# ?

2023-05-01T11:24:00.006+05:30

In this blog, we will learn how to test the performance of the C# code. For the performance, we will use benchmarking.

Benchmark

Benchmarking measures how well a piece of code performs; it evaluates the code and aids in performance improvement. We utilized the Benchmarkdotnet package to carry out the benchmarking in C#.

BenchmarkDotNet

BenchmarkDotNet is a nice tool that provides a simple way to make an informed decision about the performance metrics of your application. In BenchmarkDotNet, the invocation of a method that has the Benchmark attribute set is known as an operation. An iteration is the name given to a collection of several operations.

A small, effective, open-source.NET framework called BenchmarkDotNet may turn your processes into benchmarks, monitor their effectiveness, and share reproducible measurement tests. It isn't more difficult than writing unit tests.
In this project, there are two methods we must use to call an API: one is Httpwebrequest and the other is Rest Sharp.
We have therefore contrasted these's performances using the benchmark.

To begin,
we build an Asp.net Core MVC project. Next, we visit the Package Manager Console.

add the benchmark NuGet package

Steps for benchmarking code using BenchmarkDotNet

To run BenchmarkDotNet in your .NET Framework or .NET Core application you must follow these steps:

1. Add the necessary NuGet package

2. Add Benchmark attributes to your methods

3. Create a BenchmarkRunner instance

4. Run the application in Release mode

Create a benchmarking class in .NET Core

Open the Program.cs file and write the following code in there.

[MemoryDiagnoser]
   public class MemoryBenchmarkerDemo
    {
        int NumberOfItems = 100000;
        [Benchmark]
        public string ConcatStringsUsingStringBuilder()
        {
            var sb = new StringBuilder();
            for (int i = 0; i < NumberOfItems; i++)
            {
                sb.Append("Hello World!" + i);
            }
            return sb.ToString();
        }
        [Benchmark]
        public string ConcatStringsUsingGenericList()
        {
            var list = new List<string>(NumberOfItems);
            for (int i = 0; i < NumberOfItems; i++)
            {
                list.Add("Hello World!" + i);
            }
            return list.ToString();
        }
    }

In the Main method of the Program.cs file you must specify the initial starting point — the BenchmarkRunner class.

Run the benchmark in your .NET Core application

Running benchmark code in debug mode will result in an error.

Hence you should run your project in the release mode only. To run benchmarking, specify the following command at the Visual Studio command prompt.

dotnet run -p BenchmarkDotNetDemo.csproj -c Release

When you run this command, the benchmarking process kicks off and displays the output after the benchmarking process has been executed successfully

Improving Performance with OutputCache

2023-04-26T23:55:00.003+05:30

💡 ASP.NET Core Output Caching Middleware boosts web app performance by caching HTTP request output in memory. This reduces server workload, resulting in faster response times and better user experience. Let's take a look at what it is and how to use it 👇

– Also, we can change the default expiry time of the Base Policy, in the third code example we have changed the expiry time of the base policy and set it as 5 seconds.

Overall, using Output Caching can be a great way to improve the performance of your web application. By caching the output of frequently accessed endpoints, you can reduce the load on your server and provide a better user experience for your visitors. Just be sure to use caching wisely and consider the potential impact of caching on your application's behavior and data consistency.

Example:

using System.Web.Mvc;

namespace MvcApplication1.Controllers

{

[HandleError]

public class HomeController : Controller

{

[OutputCache(Duration=10, VaryByParam="none")]

public ActionResult Index()

{

return View();

}

Redoc - Instant API documentation

2021-03-01T23:53:00.013+05:30

Introduction:

In this article, we will explore the best API documentation tool.

THE BEST FREE API DOCUMENTATION TOOL

There are plenty of tools available for doing API documentation - some are open-source.

Today, I have found an advanced ease solution called Redoc - Easily deployable API documentation. 😇

Redoc Community Edition is a free open-source software.

https://redoc.ly/redoc

Redoc is an open-source tool that generates API documentation from OpenAPI specifications. It’s one of the most powerful free docs tools in the industry, producing clean, customizable documentation with an attractive three-panel design. With support for Markdown, it allows you to write and style descriptions with ease.

By default, Redoc uses a three-panel layout:

The left panel features a search bar and navigation menu.
The central panel contains the documentation itself.
The Right panel contains request and response samples.

Demo - http://redocly.github.io/redoc/

Github - https://github.com/Redocly/redoc

Installing Redoc in under 5 minutes.

Create a basic html page with default tags and add redoc tag and add the JavaScript reference for redoc.standalone.js

Ex:

<!DOCTYPE html>

<HTML>

<head>

<title> API Documentation</title>

</head>

<body>

</body>

</html>

Redoc supports OpenAPI (OAS2 and OAS3)

Redoc supports advanced OpenAPI v3 declarations like nested objects, the discriminator, “one of”, “any of”, “all of”, or nullable, and callbacks that aren’t supported properly in competitor tools.

Swagger UI

Swagger UI is the best-known solution for generating API documentation. However, the design is outdated when compared with Redoc.

https://swagger.io/tools/swagger-ui/

Conclusion:

Redoc is the best choice and it looks great for the open-source solution also it is easy to implement.

2020-01-03T14:33:00.000+05:30

Introduction:

In this article, we will explore How to configure two apache tomcat instances in the same machine both Windows and Linux?

Configuring Tomcat port

By default tomcat binding ports are 8005, 8080 and 8009.

If you have another tomcat instance running on same server or other application like JBoss Application Server, these ports are likely already used. In this case you should change the default ports.

Change tomcat ports

The port change must be done with the tomcat application stopped.

Edit $TOMCAT_Home/config/server.xml and check all Tomcat port properties.

Shut-down Port	8005	8105
	Change <Server port="8005" shutdown="SHUTDOWN"> to <Server port="8105" shutdown="SHUTDOWN">

Tomcat Connector Port	8080	8180
	Change <Connector address="0.0.0.0" connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443"/> to <Connector address="0.0.0.0" connectionTimeout="20000" port="8180" protocol="HTTP/1.1" redirectPort="8443"/>

AJP Connector Port	8009	8109
	Change <Connector address="127.0.0.1" port="8009" protocol="AJP/1.3" redirectPort="8443"/> to <Connector address="127.0.0.1" port="8109" protocol="AJP/1.3" redirectPort="8443"/>

To shut-down the different instances execute the shutdown.sh script from each $TOMCAT_HOME/bin.

"Unable to display this Web Part" sharepoint error with custom XSLT applied to list contains Large number of items

2018-03-27T18:42:00.001+05:30

Introduction:

In this article we will explore, How to solve the SharePoint Web Part error “Unable to display this Web Part “while using custom XSL

PROBLEM:

"Unable to display this Web Part. To troubleshoot the problem, open this Web page in a Microsoft SharePoint Foundation-compatible HTML editor such as Microsoft SharePoint Designer. If the problem persists, contact your Web server administrator.

Correlation ID: ae93579e-b40d-c07b-d97e-f14105eec10f"

Error while executing web part: System.StackOverflowException: Operation caused a stack overflow. at <xsl:apply-templates>(XmlQueryRuntime , XPathNavigator ) at <xsl:template match="dsQueryResponse">(XmlQueryRuntime , XPathNavigator ) at <xsl:apply-templates>(XmlQueryRuntime , XPathNavigator ) at Root(XmlQueryRuntime ) at Execute(XmlQueryRuntime ) at System.Xml.Xsl.XmlILCommand.Execute(Object defaultDocument, XmlResolver dataSources, XsltArgumentList argumentList, XmlWriter writer) at Microsoft.SharePoint.WebPartPages.DataFormWebPart.ApplyXslTransform(XPathNavigator dataNavigator, XslCompiledTransform xslCompiledTransform, XsltArgumentList xmlArguments) at Microsoft.SharePoint.WebPartPages.DataFormWebPart.ExecuteTransform(XslCompiledTransform xslCompiledTran... ae93579e-b40d-c07b-d97e-f14105eec10f

WORKAROUND:

This happens because the time allocated for XSL transformation is lesser while loading large number of records in the page.

By default Sharepoint allocates 1 second for XSL transformation.

SOLUTION:

To solve this issue, we need to increase the timeout seconds in Sharepoint FARM for xsl transformation.

Open Sharepoint Management Shell with "Run as Administrator"

Steps:
=====

Check Current Setting

$farm = Get-SPFarm
$farm.XsltTransformTimeOut

$farm = Get-SPFarm

$farm.XsltTransformTimeOut

The default setting is 1 second ,Now increase the timeout to 5 seconds as below.

(increase timeout seconds based on your page loading time)

$farm = Get-SPFarm

$farm.XsltTransformTimeOut = 5

$farm.Update()

Now the issue fixed, refresh the page to view the list items.

Reference: https://blogs.msdn.microsoft.com/bkr_sharepoint/2014/06/08/no-xslttransformtimeout-property-found-in-sharepoint-farm/

http error 503. the service is unavailable in IIS after enabling 32 bit application

2015-10-08T00:16:00.000+05:30

By default, IIS running on a 64 bit computer does not support running a 32 bit application. However, you can change the setting in an Application Pool under which the application is running by setting the ‘Enable 32-bit Applications‘ to true.

In IIS, I created a new web-site and change the application pool to enable 32-bit application to support my 32 bit application.

While accessing the apppplication i got the "HTTP Error 503. The service is unavailable" error.

Also Identified that the application pool was stopped repeatedly when i tried to access the application. Finally got the below error from event viewer.

The Module DLL ‘C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\15\isapi\spnativerequestmodule.dll’ could not be loaded due to a configuration problem. The current configuration only supports loading images built for a x86 processor architecture. The data field contains the error number. To learn more about this issue, including how to troubleshooting this kind of processor architecture mismatch error, see http://go.microsoft.com/fwlink/?LinkId=29349.

Solution:

Run the following command in Windows Command Prompt.



"%systemroot%\system32\inetsrv\AppCmd.exe" set config -section:system.webServer/globalModules 
/[name='SPNativeRequestModule'].preCondition:integratedMode,bitness64

This will solve the problem to load SPNativeRequestModule when the application pool is running in Integrated Mode and 64-bit application mode.

Hope the issue solved !!

retrieving the com class factory for component with clsid 80040154 Retrieving the COM class factory for component with CLSID {...} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)

PROBLEM:

When you run the .net Code in X64 Environment you will get the following error message.

" Failed --Retrieving the COM class factory for component with CLSID ...."

E.g. in Retrieving the COM class factory for component with CLSID {94773112-72E8-11D0-A42E-00A024DED613} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)

WORKAROUND:

The possible workaround is modify your project's platform from 'Any CPU' to 'X86' (in Project's Properties, Build/Platform's Target)

ROOTCAUSE

The VSS Interop is a managed assembly using 32-bit Framework and the dll contains a 32-bit COM object. If you run this COM dll in 64 bit environment, you will get the error message.

SOLUTION

Open IIS
Select the application pool used by your website
Click Advanced setting
enable 32-bit Application to TRUE which was set to False by default.
Restart IIS
Now its resolved. :)
