Oops, you're right HZ is 100 not 1000.

Re: what is the granularity of itimer
itimer is based on jiffies, so the granularity should be 1 millisecond (HZ=1000/s) in kernel space. I haven't tested this, though.

what is the granularity of itimer
Does anyone know what the granularity of itimer is on a z900 (RHEL 4u3)?
