    We have a server with IIS running on it . There are many w3wp.exe processors.Once we start IIS,it will use all of the disk IO.

    How can I find which w3wp.exe processor causes this issue?

    I hope to find a general way to directly locate the process which exhausts the disk IO.
    Not just IIS process,it's just a sample.

    ProcessMonitor just can monitor the behavior of processes,I don't think it can monitor the disk IO usage of processes

    Hi,

    As suggested by Dave, this "w3wp.exe" processor can be directly related to IIS. Please seek help in IIS forum. There you can get more effective suggestion by other experts who familiar with this topic. Your understanding is appreciated.
     
    Have a nice day.
