Good advice - ZFS can use quite a lot of CPU cycles. A low-end AMD
quad-core is
I know "a lot of CPU cycles" is a relative term. But I never notice CPU
utilization, even under the heaviest loads I can generate. Note: I'm not
generally using compression (which will require CPU) and I'm not using
dedupe (which will require RAM).
Still, I don't think it's fair or accurate to generalize and say "ZFS will
use a lot of CPU cycles," unless you're qualifying it specifically such as
"if you have compression enabled."
I was wondering about that too because I've been seeing a lot of zfs
builds with atom processors and haven't complained about cpu utilization
given a small home server application.
Sid question... I recently ran across this blog post that indicates
raidz and raidz2 don't increase performance over single drive
performance unlike raid5. The post was old so I was wondering if that
was still true.
