samba - Jul 2006 - Slow Transfer Speeds (I have read the HOWTO)

Hello,

I've been having a few troubles with samba 3. I can only get 4MB/sec 
writing to the FreeBSD server that it is running on. As its on a 100Mbit 
network I was expecting at least 6-7MB/sec.

I've included the smb.conf below is there anything obvious that I have 
missed from the config that can be seen as a performance gain or does 
anyone have any ideas for non samba items that can increase the write speed.

Cheers
Richard

Tule of thumb for socket options:  Don't set this unless
you can explain why you need them.

Just realized I replied to the person and no the list :( Try again

Anyhoo, I've tried it with socket options commented out, TCP_NODELAY 
only and with the SO options in there and I see no difference in the 
amount of data that is being sent.

I've put this machine and the server on its own switch to factor out the 
router and done some more testing. Read speeds are 6MB/sec and write 
only half of that at 3MB/sec. TO be fair the read speeds are ok as are 
the dir listing speeds its just the write performance that I am having 
problems with.

Does anyone have any more suggestions.

Cheers
Richard
