I have an ASP .NET Website hosted on IIS 7.5 Win 2008 Server R2. When a load test is performed for my website, we have observed a pattern. For the first 15 minutes, the website is performing very good with acceptable transaction times. However, exactly after
15 minutes the page responses and the transaction times increase deteriorating the performance going further. In a given span of less than 10 minutes, we have 400 virtual users logging in and performing different functions. I do not think the issue could be
due to the 15 minute idle timeout setting in IIS. In the 15 minute idle timeout case, the system will slow after 15 minutes and then loads faster for subsequent hits. This is not the case. Is this pattern due to some other setting in IIS or HP Loadrunner?
Kindly help.
If you need advice on HP LoadRunner, you should go to HP. If you want to know what leads to the slowness on IIS side, IIS worker process hang dumps and performance counters may tell you. You may open a support case via http://support.microsoft.com with Microsoft
if you are not familiar with IIS troubleshooting.

Hi , I know this is quite a old post and I am sure you must have found some solution for your problem that you had faced.
Well, even I been facing similar problem with my load testing ....my test is fine for the first 5 minutes and after that , iis goes to a hang state and comes back again after 5 minutes....
Hi there , actually my problem was solved , it was to do with the objects as the Non-disposal of the WCF service proxy objects was resulting in reaching the maximum number of proxy objects. Consequently only 15 concurrent users could access the web service
concurrently.
