zfs discuss - Jun 2008 - Performance issues ZFS / CIFS on home file server

I''m setting up a home file server on opensolaris b86
My system is running with  AMD Athlon 4400+, 1GB ram, rge 100Mb/s ethernet

I''m able to create the CIFS shares and able to access the data from my
windows laptop. Now, when i try to stream some HD video the performace is pretty
bad, to the extent that the video is not watchable.

I tried to set the ZFS arc max setting to 50MB but that did not help. I do see
that my available physical memory becomes very low ~40MB.

can any one help?

Thanks in advance. 
Vijay

Do you know that the network is good ?

I''d recommend using iperf[1] to first check you have a good network 
connection between Windows and Solaris.  The reason I says this is 
because I''ve seen similar issues with two friends setting up a similar 
thing.

For streaming video you might actually be better off using a upnp media 
server on the Solaris system such as mediatomb[2].

I''ve had issues with the rge driver. Write TO the zfs box was good, but
read FROM was terrible. Granted, this was likely a different Realtek chipset as
mine was gigabit, but it could be having the same issue. Try the gani driver
(use Google to find).

Yes i tried using iperf. I''m getting ~85 Mb/sec. That rules out network
as suspect.

Yes I saw somewhere in the forums about this. do you know what chipset was it?.
Mine is RTL8111/8168B.

As i said in my previous post I''m getting ~85 Mb/s.

The Realtek chipset I was using was RTL8111B on an Asus P5B, which is the same
"family" as yours, so I don''t think you can rule out the
network. Give the gani driver a shot.
