Hi.
Between 2 linux (2.6.11 client and 2.6.14 server) machines connected by
a 100Mb link I get samba performance copying a file from the client to
the server through a smbmounted share of around 4.2MB/s
Is this to be expected? Or can it be improved (and if so, how?) I've
tried tweaking SO_(SND/RCV)BUF (after reading numerous articles on
samba performance...), but it doesn't seem to have any effect.
Unfortunately, I can't use jumbo frames at this moment either.
I've tried this with shares on ReiserFS and XFS and there is no
difference in the transfer rate.
Both machines are not even close to maxxed on cpu (both are at around
10-15% cpu when the transfer is running).
Thanks.

Have a look at:
http://www.drouillard.ca/Tips&Tricks/Samba/Oplocks.htm
Basically, it comes down to try this:
socket options = TCP_NODELAY SO_SNDBUF=65536 SO_RCVBUF=65536 IPTOS_LOWDELAY
lock spin time = 15
lock spin count = 30
