Sometimes slow response on routing RRS feed

  • Question

  • User1532951984 posted

    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.

    Any idea?

    Thanks in advance - Ton

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

    Unfortenaly this is not the case because 1 minute before there was still activity. But thanks for the suggestion

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

    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.
