In particular, is the CPU spending most of its time responding to IRQs, or in Wait-IO (wio)? If files are still showing as nobody after the above changes, edit /etc/idmapd.conf, ensure that Domain is set to FQDN minus hostname. To specify the user and group IDs to use with remote users from a particular host, use the anonuid and anongid options, respectively.
