I am using Telerik's Test Studio for evaluating the same for functional testing of the application and so far we are successful with the evaluation of the tool. I was wondering if I can use the same for Performance testing of the application as the tool offers the same also. Till now we are using HTTP Watch for the performance testing of the application, but unlike Test Studio that doesn't offer automation of scripts. So, I tried the Test Studio for the same scenario as we use to do with HTTP Watch and found that there is difference of timings provided by both the tools i.e. if HTTP Watch shows 1.7 secs. then Test Studio gives 3.5 secs. in its result for multiple iterations there is approximately same difference among the results of the both tools.
Please let me know if there is any specific reason for this difference or how can I calibrate the results.
Thanks & regards,
