Re: [Samba] Increasing samba performance

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 t=

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 ha=

performance problems using 2 Linux boxes in past kernels - I don't remember
when it was solved, but it works beautifully now.
