We have a asp.net 2.2 controller. The only thing the method does is a WCF call to an already existing service hosted in the same IIS on a different port.
We have a performance tester on a different computer which does:
1) Do the WCF call the controller does and measuring the performance
2) Do the controller method call measuring the performance.
It runs fast the whole night but random about 20 times per night the controller call is slow. Sometimes even 20 seconds.
The WCF call is ALWAYS fast.
Thanks in advance - Ton

Maybe the application spun down due to non-use and you are seeing a delay due to startup.

or the app crashed (or you have a memory leak), and recycled. check your error logs.

This is not the case

Other factors are processes running on the machine(s) like batches or maintenance.
I assume your logs have more information like the times of the slowness and the code that was running? You are in the best position to troubleshoot this issue. All we can do is guess... Make a plan and troubleshoot.
