I'm averaging 120,000+ emails (mostly mailing lists) a day on just an
Ultra 10 333Mhz, 512MB Ram, and IDE HD's, and it rarely shows more than
1-2% utilization, so, I'm not sure that helps, but maybe it gives you
some reference point to go on. It certainly seems your setup should be
running far lower on utilization. Are you running it in inetd? or
tcpserver? (etc).
