Hi all

I just ran these tests on my network and came up with these results.
I found it interesting and thought I would share.

In all test the same 2.5 Gig logfile was used for transfer
(2719312019 Nov 12 11:42 maillog.back)
(2.5G Nov 12 11:42 maillog.back)
The transfer was done over two Gigabit nic's one onboard broadcom on IBM 
X440 server, Other Intel on standard selfbuilt dual P3 880 machine.
Both servers are running Red-Hat Linux
Coping from dual P3 800 3Gig ram Seagate Cheetha 10 000 rpm disk
to dual P4 Xean mp 6Gig ram 6xdisks in raid5e

Anybody wish to comment on this?
Any ideas to make it even faster?
I have to
