Did anyone try disabling the onboard NIC and put in an Intel
Pro/1000 in the PCI express slot in the server and retest with
both Linux and FreeBSD? As I run Proliants for a living,
this stuck out to me like a sore thumb. The onboard NIC
in the systems they used for the testbed is just shit. Hell,
just about anything Broadcom makes is shit. They even managed
to screw up the 3c905 ASIC when 3com switched to using them
as the supplier (from Lucent)( - I've watched those card versions
panic Linux systems and drop massive packets in FreeBSD,
when the Lucent-made chipped cards worked fine.

It's customary in the industry before publishing rather unflattering
results to call in the team in charge of the unflattering
product and give them a chance to verify that the tester
really knew what they were doing.
FreeBSD has got slammed a number of times in the past by
testers who didn't do this. In fact as I recall the impetus
for fixing the
extended greater than 16MB memory test was due to a
slam in a trade rag from a tester who didn't bother
recompiling the FreeBSD kernel to recognize the complete
amount of ram in the server, and running it up against Linux.
Maybe I am wrong and the ISC team did in fact call you guys
in before publishing the results - but the wording of
the entire site (not just the test results) indicated
they did their testing and informed FreeBSD after the fact.
after publishing. Not nice.
