    Hi,


    I work for a small company which sells computer vision equipment. They have an industrial camera connected to the LAN port on a PC. We are currently using Windows 7.
    Recently, I have tested our software with Windows Embedded Standard 7, and I have noticed a decrease in the performance of the equipment. In order to find out the problem, I have used Windows Performance Toolkit. I have noticed that, with Windows 7, the DPC CPU Usage is shared between the 2 cores of the CPU, but with the Embedded edition, all the DPCs are managed by the same core. I guess that this is what is causing the decrease in the performance.
    The problem is, that I do not know how to change this. Is there any setting, command or something, that could help me?


    Thanks in advenced

    Run MSCONFIG, select BOOT tab, Advanced options..., number of processors = 2, OK, Make all boot settings permanent =√, OK, Restart

    this improves nothing. Having the option Unchecked means it always uses all cores.
