Alternatively, take your favorite test programs, such as John's,
and make a second pair that reverses the direction the data is
sent. So one pair is server sends, the other is server receives,
try both. That's where we started, BitKeeper, my stripped down test,
and John's test all exhibit the same behavior. And the rsh test
is just a really simple way to demonstrate it.
Netperf TCP_STREAM - server receives. TCP_MAERTS (STREAM backwards) - server
sends:

between a pair of 1.6 GHz itanium2 montecito rx2660's with a dual-port HP A9900A

back-to-back rather than through a switch. I'm afraid I've nothing older installed.

Where I do have things connected via a switch (HP ProCurve 3500 IIRC, perhaps a
2724) is through the core BCM5704:
