problem profiling ASP.NET application in IIS

Post by antananar »

ASP.NET
.NET 4
IIS 7.5, 64-bit
Windows 7

I tried to profile ASP.NET application in IIS loaded with 10 jmeter threads and the profiler freezes and the application is not serving any request after 2 mins of profiling.
Profiling same application loaded by 50 jmeter thread on WebDev server of VS2010 was fine.
I noticed that it freezes even without sampling, freezes with sampling too.
When sampling was running I can take a snapshot of couple of minutes of data before the freezing. But is is not enough. The application cycle is much larger than 2 minutes.

Without your profiler application runs fine with 50 thread jmeter load.

I need to profile in IIS working process because my app behaves differently there.

Can you please advise to overcome this problem?
Thanks
