Hello! I''am setup zfs / cifs home storage server, end now have low performance with play movie stored on this zfs from windows client. server hardware is not new , but n windows it perfomance was normal.

They changed their ethernet adaptor to an Intel ethernet interface and the performance problem went away. It was not ZFS''s fault. 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.

The drivers for hardware Realtek and other NICs are ... not so great. -B -- Brandon High : bhigh at freaks.com

thanx all, i think it''s hdd & nic summary perfomance degrade. i try to replace it , and hope can see my movies ;)) -- This message posted from opensolaris.org
Are you able to qualify that a little? I''m using a realtek interface with OpenSolaris and am yet to experience any issues. Nathan.

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 : bhigh at freaks.com
Interesting. I''ll have a poke... Thanks! Nathan.
