I have done many tests to try to determine the poor performance on my
systems (FreeBSD-current connected directly to Windows XP via identical
Intel Pro 1000 cards) and my only conclusion is that Samba on FreeBSD
when talking to a Windows box is simply fubared. Im willing to bet thats
not the case on Linux. I can get great speeds (~30MB/s) using ftp
between the machines, but when i use Samba, i get a maximum of 11MB/s. I
have tried playing with mtu size, samba options, polling, but there does
not seem to be any visible bottlenecks, its just simply slow. It would
be great if someone could get to the bottom of this, its quite
frustrating.
There are a number of TCP related configuration frobs on FreeBSD. It
would be quite interesting to know how modifying each of the following
settings affects Samba performance:
net.inet.tcp.delayed_ack
net.inet.tcp.sack.enable
net.inet.tcp.inflight.enable
There has been recent evidence that the inflight bandwidth calculation is
having problems generating stable performance at high bandwidth and low
latency, so I might try that one first.
