I think there are options here, but there are few who will care enough to spend the time required to optimize... it is less expensive to buy lower-power processors than to spend even one man-hour trying to get savings out of a high-power processor. But if you are up to the challenge :-) try disabling cores entirely and leave the remaining two or three cores running without C-states. You will need to measure the actual power consumption, but you might be surprised at how much better that works for performance and power savings. -- richard _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
