Hello,
I am using OpenBSD on laptop (desktop use cases). Linux defaults for 250 HZ system clock's frequency and for desktop use cases it is suggested in Linux to have at least 250 HZ system clock's frequency. For users wishing to have highly responsive systems it is suggested to have 1000 HZ frequency.
Code:
sysctl kern.clockrate
kern.clockrate=tick = 10000, tickadj = 40, hz = 100, profhz = 100, stathz = 100
tells me that in OpenBSD, by default, it is not the case.
I have grep-ped source code of OpenBSD kernel and found that I can append this line:
to /usr/src/sys/arch/amd64/conf/GENERIC file. After building and installing kernel from source I have:
Code:
sysctl kern.clockrate
kern.clockrate=tick = 1000, tickadj = 4, hz = 1000, profhz = 1000, stathz = 1000
1. Does anybody use that option and could write whether system is stable after this change?
2. I guess that kernel with changed options is not supported by OpenBSD. Am I right?
