Interesting - I have a E6600 also, and I will give this a try. I left 'cpupm enable' in /etc/power.conf because powertop/prtdiag properly reported all the available P/C-states of my CPU, so I assumed that power management was good to go. What do you have cpu-threshold set too? (This may be a moot point for me, because my CPU is littering fault management with strings of L2 cache errors, so might be upgrading to Nehalem soon). _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
