Hmmm.

I've gotten 85-100 Mbps with our ENI cards between two P133's.
I used Rick Jones' netperf to get this 
(see: http://www.cup.hp.com/netperf/NetperfPage.html)
I used one of the following command lines:

./netperf -l 60 -H 128.252.200.1 -t TCP_STREAM -- -m 1048576 -s 131072 -S 131072
./netperf -l 60 -H 128.252.200.1 -t TCP_STREAM -- -m 1048576 -s 245760 -S 245760

I seem to recall getting 120Mbps if I used UDP rather than TCP.
