Is it spinning the CPU? cmp big_file /other_disk/big_file Cmp is running slower than it should. It isn't cpu bound ( 67.5%Idle ) but it isn't disk bound either. Seems like it should be one or the other. _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-performance To unsubscribe, send any mail to "[email protected]"
