  • Hi Sudip_inn,

    Thank you for posting here.

    Questions about setting up performance monitors can be asked in Windows Support, I rarely use it and am not familiar with it.

    And what I want to say is that multi-threaded programs do not necessarily use all the cores.

    In the past, I used Java to do an experiment and run a 4-threaded program on a 4-core computer. If the calculation of the thread is very simple, threads are not necessarily evenly distributed.

    But I haven't tried it with C#, so I'm not completely sure about this, but I think this should belong to the CPU's scheduling algorithm.

    So even if there is a way for the performance monitor to show how many CPU cores are being used, that is the use of the whole computer, not the use of this winform program.

    Of course, C# provides a method to allow a thread to run on a specific CPU core. This method may accurately count how many CPU cores the program will use, but this is not a good idea in general, it will reduce the overall efficiency.

    Best Regards,
