My uneducated guess is that without the SSD, the disk performance is low enough that you don't need that much memory.. with the SSD, performance goes up and so does memory usage due to caches.. Limiting the ARC or lowering the flush timeout might help.. /Tomas -- Tomas Ögren, [EMAIL PROTECTED], http://www.acc.umu.se/~stric/ |- Student at Computing Science, University of Umeå `- Sysadmin at {cs,acc}.umu.se _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
