[Samba] Increasing samba performance

[John McCain]

You are definately getting sub-par performance.  The difference between
where you are and where you need to be is not tweaking.  We run Samba right
"out of the box" for a high-speed realtime requirement, and we don't have to
tweak it at all to get 40 or so megabytes/sec out of it with properly
configured servers and gigabit networking.  And we could probably push it
harder if we want to  - we're getting high responsiveness at that level.

I would look at the client side of the problem - try a newer kernel.  We had
performance problems using 2 Linux boxes in past kernels - I don't remember
when it was solved, but it works beautifully now.
