1.9.16-patched performance

[Sundar Narasimhan]

Hi Jeremy: Does this mean that the right way to handle 100B-T networks
is to take out the TCP_NODELAY socket option? I'm curious why the
performance went down with the switch though. 

I'll try out the patched version you suggest at some point.

Do you have TCP_NODELAY set as a socket option in your smb.conf ?

If so, this could cause the problem as every write from
Samba will then generate a packet.

Upgrading to 1.9.18p2 with oplock support will also
help greatly.
