Did you restart the samba service after changing the socket options?
Performance will also be dependent on the hardware configuration of
the clients/servers. It has been pointed out that with the latest
Linux 2.6 kernels, you need not specify SO_SNDBUF and SO_RCVBUF. Were
you measuring the READ or WRITE performance with this Samba server?

Hello,
I try to find out how can I improve the performance of our samba
installation. For this I install a testbed with a linux server (samba
and nfs), a linux client, a windows 2003 server and a windows XP client.
All computers are connected with gigabit ethernet.
If I use NFS between the linux client and server I get 65MByte/sec,
which is quiet a nice performance.
If I use CIFS between the linux client(smbmount) or windows client and
the samba server I get only 16MByte/sec.
If I use CIFs between the windows client and windows server I get
35MByte/sec. This the more than double speed of the samba server.
What can be the reason for these different speeds? How can I improve the
performace of my samba server. I play around with socket options and max
xmit option. But this does not help. At the moment this values are set:
socket options = TCP_NODELAY IPTOS_LOWDELAY SO_KEEPALIVE
SO_SNDBUF=65536 SO_RCVBUF=65536
max xmit = 65536
I find out, that I can speedup the connection between linux client and
server if I use smbclient with the option -b 15000 . Than I get 30MByte/sec.
How can I set this option with smbmount and on the windows client?
Thanks a lot,
Andrea
