There is a performance monitor, actually man different ways to look at performance. In general, the best view is from the client. The farther you get from the client, the less you can see. For example, using iostat on the server is a common thing to do, but since the server caches data from the disks and iostat only shows I/O requests, it will be difficult to correlate server disk I/O to client performance over time. There is a wealth of information on Solaris performance analysis and tuning knowledge available on the net. -- richard _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
