Hi, > ``` > beast3:util.nightly[main]$ cat /proc/config.gz | gunzip | grep CONFIG_HZ > # CONFIG_HZ_PERIODIC is not set > # CONFIG_HZ_100 is not set > # CONFIG_HZ_250 is not set > # CONFIG_HZ_300 is not set > CONFIG_HZ_1000=y > CONFIG_HZ=1000 > ``` > > Which means the Linux scheduler wakes up every milisecond to re-time-slice running processes... a good default for interactive systems, but maybe too much added overhead/cost for longer running compute intensive stuff. I never understood why this cannot be configured at runtime but needs compile-time changes. Something to put into /etc/sysctl.d/ would be ideal. Maybe it can be done.
