slowness tracing with xperf

 Install the Windows Performance Toolkit (http://social.technet.microsoft.com/wiki/contents/articles/4847.install-the-windows-performance-toolkit-wpt.aspx), open the command prompt with admin rights.


    Now run this command and capture the issue:

    xperf -on BASE+LATENCY+DISPATCHER+POWER -stackwalk profile+CSwitch+ReadyThread -buffersize 1024 -MaxFile 512 -FileMode Circular && timeout -1 && xperf -d SlowWindows.etl


    If you have enough data (30-60s), press a key to stop tracing.

    zip the SlowWindows.etl as 7z/RAR (to reduce the size), upload it (Skydrive, dropbox) and paste a link here.
