The impact of CPU time on test response time during Load Test RRS feed

  • 问题

  • Hi, All

    I'm doing  a web performance testing with VS 2010 ultimate,and I put VS,1 controller and 1 agent together on a VM with configureation of two 2.6GHz processor and 5G RAM.

    With this resource limitation, I can only generate around 280 concurrent users, over this number, the CPU time will over 75% and meanwhile, the page response time start to rise to an unusual level.

    But in theory, the response time is the average time to receive the entire response to a request, measured from the time the request was sent to the Web server. It's nothing related with test client CPU. So how exactly the CPU time impact the web load test response time calculation?
