Have you tried the iperf suggestion? First on the server, open up
TCP port 5001 on the firewall (just is just temporarily--iperf
defaults to port 5001), then run "iperf -s" on the server.

On the client, run "iperf -c ip-address-of-server" and wait, oh, 15
seconds or so. Both the client and server should show some results.
This is from my laptop as the client over a 100Mbps wired link to my
server (yes, it's an old laptop with a built-in 100Mbps NIC):

[root@golem4 ~]# iperf -c 192.168.1.50
------------------------------------------------------------
Client connecting to 192.168.1.50, TCP port 5001
TCP window size: 85.0 KByte (default)
------------------------------------------------------------
[  3] local 192.168.1.52 port 38964 connected with 192.168.1.50 port 5001
[ ID] Interval       Transfer     Bandwidth
[  3]  0.0-10.0 sec   112 MBytes  94.2 Mbits/sec

So, over my 100Mbps wired link, I got 94.2Mbps.
