Good luck. It appears that tuning smbd and clients, both Windows and
smbclient, to get anywhere close to wire speed is somewhat of a black
art. I asked the same question many months ago, and dropped the subject
after Jeremy said it had to be a problem with the W2K redirector. Funny
thing is, that same W2K redirector can pull at almost wire speed from a
WinXP box. The most I've ever been able to get out of smbd is ~8MB/s.
I'm running 3.2.5-4lenny12. To get anything better than that I'll have
to go to GigE. I probably won't get anywhere close to wire speed, but I
should get at least 30-40MB/s, which is 4-5 times what I get now, and
would thus be a huge improvement for relatively little cost--a few NICs
and a decent desktop GigE switch can be had for around $100 USD. Even
without using jumbo frames this would be a huge improvement over 100FDX.
