I see the likes of: load averages: 0.20, 0.22, 0.25 in top -SIaocpu . The list of non-idle, non-zero WCPU% columns is usually something like: 0.05% top -SIaocpu 0.03% [clock] 0.01% [intr] 0.01% [usb] Sometimes there is also something like: 0.03% [acpi_thermal] or: 0.01% [kernel] Less often (varies more widely but is non-zero less often): 0.15% [zfskern] There are also a number of processes listed with 0.00%, such as (expect some overlaps with the above): 0.00% /usr/sbin/mountd -r /etc/exports /etc/zfs/exports 0.00% sshd: markmi@pts/1 (sshd) 0.00% /usr/sbin/ntpd -p /var/db/ntp/ntpd.pid -c /etc/ntp.conf -f /var/db/ntp/ntpd.drift -g 0.00% [intr] 0.00% [pagedaemon] 0.00% [bufdaemon] 0.00% [rand_harvestq] 0.00% [zfskern] 0.00% [syncer] 0.00% [vnlru] 0.00% [acpi_cooling0] Truely zero CPU usage processes are not listed. Definitely doing somewhat more than nothing, as is normal for so-called "idle" as far as I know. What about this would make the load averages unreasonable? (I'm also not aware of any sort of technical accuracy criteria being claimed for the load averages. More general judgments are involved about good-enough instead.)
