Other people have already corrected you about ramdisk for log. It's already been said, use SSD, or disable ZIL completely. But this was not said: In many cases, you can gain a large performance increase by enabling the WriteBack buffer of your ZFS server raid controller card. You only want to do this if you have a BBU enabled on the card. The performance gain is *not* quite as good as using a nonvolatile log device, but certainly worth checking anyway. Because it's low cost, and doesn't consume slots... Also, if you get a log device, you want two of them, and mirror them. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
