I am testing SAMBA and SAMBA Client on a switched Gigabit Ethernet network. On same network, a Win2K client writes to a Win2K Server at about 16 MBytes/sec. The Win2K client also writes to a RH 7.2 Server with SAMBA at about the same 16 MBytes/sec. But when I try a SAMBA client throughput drops to about 4.5MBytes/sec to either the Win2K Server or the Linux Samba Server. I've tried this with both RH 7.1 and RH 7.2. clients with similar results. There doesn't seem to be much to tune on the samba client side. I've tried IPTOS_THROUGHPUT, TCP_NODELAY, and SO_SNDBUF (at various sizes) and none of it shows a significant change in performance. Can anyone tell me how to effect the performance of a linux samba client writing to a Win2K Server or Linux Samba Server. By the way, Server to Client performance is also in the 16MBytes/sec range. It is just writing to the server that is slow. Thanks.
