Hi Shankar,

You should probably start with the overview of load test analyzer at http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=922674&SiteID=1. The Web and load testing forum also has a Load test faq by Yun Tong at http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=482304&SiteID=1.

Hi,

Please clarify the following doubts

I worked with 2 load testing tools testcomplete and load runner and i have the following queries.

How do we trust that realtime 5 realusers and load testing tool 5 virtual users have the same request time and response time or other performance calculations?

Is it possible to check the performance testing by manual?

How the load testing tool recognizing the users and simulating into many virtual users?

How the load testing tool using proxy servers and protocols?

Thanks,
Shankar

Hi ramesh,

I checked the links which was given by you. Its mainly focusing on how to use the windows automation tool and not clearly mentioned on how to analyse the load testing results.

This are the following results i got when i was tested a webpage.

Based on the above this results how to finalize the response time, request time and overall performance time is okay or not?

Thanks,

This is hard to judge without knowing the application and what you expect for your end users. Please checkout this link which has guidance on performance testing: http://www.codeplex.com/PerfTesting

hi shankar,

as of my knowledge, for any general web site there will be some standards given by W3C in all aspects like speed, performance, load and so on. By taking that we can create, customer specific standards or depending on end user specifications or depending on the content of the web site and like this so many parameters are involved to prepare the customer specific standards...

thanks
