I have developed a e-commerce web application in asp.net using sql server (stored procedures and using linqtosql). I want to perform load testing, stress testing, response time for client when he requests server pages, and i also want to analyse the time the application takes to execute the sql instructions/retrieving the data from database.

How can i perform this analysis ? I'm a student in a university, so the tools that i have at my disposal are quite limited. 

Help me out !!

Thanks in anticipation
