  • Are the same services running on both?

    Using Task Manager, do you see an application that is taking up more CPU?

  • A couple other questions...

    Are the two computers exactly the same? 

    Do you have any write filters enabled on the embedded image?

  • Thanks for your reply.

    I'm using the same config, run the same application.

    However, one problem is from codecs of IP Cameras. The rore Cameras are added, the more CPU gets higher.

    I'm worrying  my action when I added too much codes from Win 7 embedded. However, I removed step by step. It's still higher.

     

    Please help!!!

    Thanks

  • Adding a bunch of USB cameras to Windows 7, the CPU doesn't go up, but in WES7 CPU goes up - correct?

    Filters - Do you have EWF or FBWF in the image? If you run EWFMGR.EXE or FBWFMGR.EXE at the command prompt, what do you get?

    Do you have the run-time license installed?

  • Thanks for you answer.

    I'm adding IP Camera via TCP/IP. on win 7, CPU doesn't go up, but in WES7 CPU goes up.

    I don't have EWF or FbWF in the image. I've license installed.

    Thanks

  • If you look at the processing running in the WES7 system do any of them look to be taking up more CPU than the others?

  • Thanks Sean.

    I've checked, but only the application with IP Cameras.

    I've aslo checked with Resource Monitor. One problem I found

    - At CPU, I see on Win 7 Pro, Maximum Frequency is 101%. On WES7, it's ~60%

    I aslo thinking, is there any difference kernel between Win 7 Pro and WES7

     

    Thanks

  • No kernel differences. Try changing the power management scheme so CPU runs at full power.

  • Hi Sean,

    I've tried to change. The result is okie now.

    Just one problem I see that Win 7 Pro don't need to change, it can get 100% Maximum Frequency.

    However, I can run well on win 7e. Thank you :)
