[macOS] psutil.Process(pid).cpu_percent calculation result is inaccurate about psutil HOT 6 OPEN

Sorry but I have no idea. I don't have the hardware to test this against. Perhaps on arm64 process CPU metrics work differently and require using a different API. It would not be a first on macOS.

How are you comparing the 2? If you want to compare with top/htop you should do it in a loop, like this:

p = psutil.Process(PID)
while 1:
    print(p.cpu_percent(interval=None)
    time.sleep(1)

@giampaolo First of all, thank you for your help. I used loops for benchmarking and there is no change. Under arm64, the cpu utilization of the psutil calculation process is very different from that of htop calculation. In addition, I use other mac (inter chips), and the calculation results are basically the same as htop.

@giampaolo Hello, please help me answer this question if you have time, it is very important to me.

@giampaolo Understood, thank you, if there is any progress in the future, please try to synchronize it. Let me investigate the specific reasons here.
