Are you able to qualify that a little? I'm using a realtek interface with OpenSolaris and am yet to experience any issues. Nathan.

There's a lot of anecdotal evidence that replacing the rge driver with the gani driver can fix poor NFS and CIFS performance. Another option is to use an Intel NIC in place of the Realtek. Search the archives for gani or slow CIFS and you'll find several people who resolved poor performance by getting rid of the rge driver. While it's not hard evidence, it seems to indicate that there are problems with the driver (and most likely the hardware). -B -- Brandon High : bh...@freaks.com ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Interesting. I'll have a poke... Thanks! Nathan. Brandon High wrote: On Thu, Jan 22, 2009 at 1:29 PM, Nathan Kroenert nathan.kroen...@sun.com wrote: Are you able to qualify that a little?

There is always the possibility that you have a slow disk drive or bad cable. Check /var/adm/messages for any suspicious messages from drivers.
