Question about mysterious delays #30

Closed tbhkuiper closed 3 years ago

tbhkuiper commented 4 years ago

This is a question for the community. I have implemented a client/server pair with callback in the manner suggested by Irmen. (Client is itself a server for the callbacks.) The server is experiencing occasional delays of a few tenths of seconds. The server has five threads, four in parallel and one collecting the results to be returned via the callback. All threads experience these delays, so that ms calculations take a few tenths of a second, roughly one time in ten. Could Pyro5 be causing this? Thanks.

Could it be that you're just seeing effects of Python's GIL?

Thank you for that.  I will investigate.

Yes, you were right. In a while loop waiting for a time to elapse I had pass instead of time.sleep(0.001). Thank you.

Incidentally, I had an audible clue I was ignoring -- the CPU fan coming on!
