Then if the scheduler always knows what's best, the backup process will be

What backup process? And why will it be uninhibited? If the system's
maxed out, all

I've seen situations where it has been useful to dedicate a core to a backup
process so the nightly backup would complete, on a busy linux
machine, with a cpuset.
If this isn't a planned feature in the near future it's not bothering me.
I'm very happy with what OpenBSD does for me.

I meant OpenBSD feature to use only CPU00 for network things.
and I am afraid it could cause network issues when some process works on
CPU00 as well.

OpenBSD is not a real-time OS.
As far as I know there's no intention to make it
I appreciate your attention for homeopathy and astrology, however I see no
relation of those to CPU00.
Maybe modern processors will handle that stuff, I don't know.

under such load server is experience somewhat to general network
delays, network conections become slow (both incoming and outgoing),
sometimes even 5 sec on 1G network.
It sounds unlikely that CPU congestion is responsible for 5 s network
delays unless your hardware is significantly

CPU00 is running at interrupt level, also there're user processes at
user and system levels.

I'm trying to keep CPU00 for network things, and avoid using it for user
applications (there're lots of CPUs).
is it possible to achive it without CPU affinity ?
