I have a DAS array with nvram so I enabled zfs_nocacheflush = 1 and it made a world of difference in performance. Does the LSI HBA have any nvram to make this tuning acceptable? Is this setting acceptable as I understood the Evil Tuning Guide? _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
