samba - Sep 2006 - Time take to copy file from Samba to Windows XP

Hello,

How much time should it take to copy 1Gb to 5Gb from from Samba server 
to Windows Xp in gigabit network?

Default Samba configs, a single copy of a 1GB file takes about 70 
seconds to complete, about 14MBps, 117Mbps, about 11% network utilization.

A Windows 2003 server, similar hardware, same network connection, can 
transfer the same 1GB file in about 28 seconds, 36MBps, 292Mbps, almost 
30% network utilization.

Apache takes 16 seconds, 64MBps, 512Mbps, over 50% network utilization.

What can be done to speed up transfer rate?

Regards,

Komal

You could increase your transfer rate changing the socket options.
Increase the SO_SNDBUF and SO_RCVBUF to bigger values such as 16384
for 16 Mbps buffer size. Test higher values for your environment.
