  • umonitor for linux uses more than expected CPU

    From Keyop Troy@1:103/705 to GitLab issue in main/sbbs on Wed Sep 20 16:56:35 2023
    open https://gitlab.synchro.net/main/sbbs/-/issues/641

    Seeing this in top on Magnum:

    1735357 sbbs 20 0 99900 7072 1748 S 13.2 0.1 431:53.04 umonitor

    So on my BBS, thats 13.2% of an Intel(R) Xeon(R) D-2141I CPU @ 2.20GHz

    And on EOTL:

    2303058 bbs 20 0 305076 17228 4184 S 17.3 0.4 0:04.06 umonitor

    Should umonitor be using so much CPU?

    Is there an opportunity to optimise umonitor when its just sat in monitor mode (default start up)?

    What happens if you pass a higher sleep value (-s option) - any change? The default idle sleep time is 100ms, which should release the process's time-slice for a minimum of 100ms (an eternity on a modern CPU).

    The correct syntax would be `umonitor -s1000` in that case, not `umonitor -s 1000`.
