Hi all,

I meet a performance problem with my customized distro of FreeBSD 6.1(FreeN=
AS).
Lot's of FreeNAS users compare the performance of FreeNAS with Linux, and
the Samba performance are very poor under FreeNAS (but not with NFS or FTP)=
.


I've use this value on the default samba configuration:
socket options =3D IPTOS_LOWDELAY TCP_NODELAY
SO_SNDBUF=3D16384
SO_RCVBUF=3D16384

But there is no change.

Then I've try to add a "tune" parameter that set this kernel variables:
net.inet.tcp.delayed_ack=3D0
net.inet.tcp.sendspace=3D65536
net.inet.tcp.recvspace=3D65536
net.inet.udp.recvspace=3D65536
net.inet.udp.maxdgram=3D57344
net.local.stream.recvspace=3D65535
net.local.stream.sendspace=3D65535
kern.ipc.maxsockbuf=3D2097152
kern.ipc.somaxconn=3D8192
kern.ipc.nmbclusters=3D60000
kern.maxfiles=3D65536
kern.maxfilesperproc=3D32768
net.inet.tcp.inflight.enable=3D0

But there is no change too... How can I improve the Samba performace ?

Thanks,

Olivier
