Re: Poor Samba throughput on 6.0

Hi Guys,

has anyone actually managed to speed up the thing up to 10-12 MB/s

i have a good 7-9 MB/s on large files and that should be enough, but still, out of curiosity?


No, not really. The performance of samba on freebsd still sucks. I have a gigabit link between my samba server and windows xp workstation, both use the intel em card. The fastest i can download from the freebsd server is 15.946 MB/s, fastest upload to is 13.594 MB/s. Thats pretty poor for a gigabit link. However, 9MB/s on your link is not bad at all, one has to consider the protocol overhead.

Oh by the way:
100 MB ethernet
ping -s 65507 -f windowshost ~ 10-12 MB/s
ftp open freebsdhost put/get 500MB.file ~ 10-12 MB/s
net.inet.tcp.inflight.enable=1 who said u have to put it down?

This feature limited the speed of LANs, however recent code has aimed to fix that, but i don't think its in 6.0. I used a recent -CURRENT for the tests, you should consider updating to -STABLE.
