asp.net application performance and stress testing ? Please guide

thanks for your attention and time.

I want to test asp.net application for stress, load and performance. Please guide me what free tools should be used for this ? Is there any tool which particularly can be used to analyse individual compon开发者_开发技巧ents, functions and scripts and resources they use ?

Thanks in anticipation for your help

Make use of :

ANTS Performance Profiler

Add-ons for Firefox Extensions Load Time Analyzer

Add-ons for Firefox Extensions Firebug

dynaTrace is a client-server web performance tool. The client part, called dynaTrace AJAX Edition, which is free, is a complete performance testing tool. It traces asynchronous JavaScript executions, including full round-trip time, and reports performance by method or event. V 2.0 Beta is just came up, and seems to be pretty stable and more powerfull than other popular and free browsers performance testing add-ons (Firebug, Yslow, etc.).

The server part of dynaTrace is designed to test ASP.NET code-level performance, but it's not free. So check this stackoverflow topic to see if any free .NET code profiles will work for you.

To test your app under the load you need to use a load generator. Check out the free Microsoft Web Capacity Analysis Tool WCAT 6.3 that allows to simulate various load scenarios.
