How to analyze the performance of requests in ASP.NET MVC application?

Question

I would like to capture the hit time, processing time, memory consumption and response time of requests in ASP.NET MVC application.

Is there any way or tool to perform this?

Answer 1

Check the miniprofiler , developed by the stackoverflow team

http://code.google.com/p/mvc-mini-profiler/

This helps you to do some analysis. There is a nuget pacakge available which you can use to add this to your project.

Scott has written a post about how to use that.

You can also look into Glimpse .

There are commerical products to do memory and performance profiling like telerik just trace . You can download their trial version and use that

You can create your own little performance test monitor. This is from page 670 of Steven Sanderson's book, Pro Asp.Net MVC 2 Framework:

public class PerformanceMonitorModule : IHttpModule
{
    public void Dispose() { /* Nothing to do */ }
    public void Init(HttpApplication context)
    {
        context.PreRequestHandlerExecute += delegate(object sender, EventArgs e)
        {
            HttpContext requestContext = ((HttpApplication)sender).Context;
            Stopwatch timer = new Stopwatch();
            requestContext.Items["Timer"] = timer;
            timer.Start();
        };
        context.PostRequestHandlerExecute += delegate(object sender, EventArgs e)
        {
            HttpContext requestContext = ((HttpApplication)sender).Context;
            Stopwatch timer = (Stopwatch)requestContext.Items["Timer"];
            timer.Stop();

            if (requestContext.Response.ContentType == "text/html")
            {
                double seconds = (double)timer.ElapsedTicks / Stopwatch.Frequency;
                string result =
                string.Format("{0:F4} sec ({1:F0} req/sec)", seconds, 1 / seconds);
                requestContext.Response.Write("<hr/>Time taken: " + result);
            }
        };
    }
}

Then add to your web.config:

<add name="PerfModule" type="Namespace.PerformanceMonitorModule, AssemblyName"/>

Not free but it is really good:

dotTrace is a family of performance and memory profilers for .NET applications.

Our latest release, dotTrace 5.2 Performance, helps .NET developers quickly find performance bottlenecks and optimize their applications.
