Are you getting lots of dropped packets on any machine?
How can I check?
Well, ifconfig will give you a basic count of errors and dropped packets as a starting point.
There are some:
eth0 Link encap:Ethernet HWaddr 00:10:DC:20:EF:D1 inet addr:192.168.1.4 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::210:dcff:fe20:efd1/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:119158 errors:2342 dropped:0 overruns:0 frame:0 TX packets:51949 errors:0 dropped:0 overruns:8 carrier:0 collisions:0 txqueuelen:1000 RX bytes:71316809 (68.0 Mb) TX bytes:54031471 (51.5 Mb) Interrupt:11 Base address:0x4000
Well, that certainly doesn't look like it would account for the speed difference.

Even though it doesn't look like a lot of errors it is. If possible try using a different nic and see if you get RX errors. Every time there is an error it causes a retransmit of the packets which will slow things down a lot.
Also try passing the kernel parameter "nolapic" at boot. I had a problem where the nic was flakey/slow and was showing errors. The kernel and the interrupt contoller were not playing nicely together. MSI mobo and Nvidia chipset. The noalpic solved the problem completely.... -- David C. Rankin, J.D., P.E.
