+1, I was having terrible problems with the onboard RTL nics..but on 
changing to a decent e1000 all is peachy in my world.

On the other hand RealTek NICs are not renowned for quality either.  
Aren't they basically the cheapest available?

Are you able to qualify that a little?

I'm using a realtek interface with OpenSolaris and am yet to experience 
any issues.

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).

 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.

Several people reported this same problem.  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.
