Hi, Aleksey:
I have three machines at home on gigabit:
A - 1.7 GHz Celeron Dell running Fedora Core 6.
B - AMD 2.9GHz dual core ("5200+") running Fedora Core 6.
C - AMD 2.0 GHz dual core ("3800+") running Windows XP.
I have the same Samba socket options as on your server. There is a Samba
server on each of the Linux machines.
Transferring the file:
A -> B 87 seconds
A -> C 95 seconds
B -> C 90 seconds
All of these are pretty close, and depending on how you count 'bps',
that's roughly 150-180 Mbps. The *fastest* transfer was Linux-to-Linux,
even though the source server is easily the slowest of the three (in all
categories - CPU, Memory, and bus speed). The gigabit interfaces are on
the motherboards on B and C, but plugged into the PCI bus on A.
When you tested the Windows client, was it on the same network
connection as the current Linux client?
Are there any network errors (e.g., retries) happening during the
Linux-Linux transfer? (Even without access to the client Linux machine,
you should be able to see them on the server end. "netstat -i" and
"netstat -s" both have useful counters for this.
Have you tried another Linux client machine in place of the 'black box'
Linux client?
