If all it takes to get Gb interfaces polling is to send Luigi a card then
he needs to send me his shipping address:)

Hello,
You might want to try out some of the Intel gigabit boards. At least
we've got an engineer from Intel who maintains the driver.
I'm far from being a FreeBSD expert, but Luigi Rizzo's polling patch
helped me a lot in similar cases to get better performance.
From POLLING(4):

Oh. Hm, maybe IPFilter 4.0 will be faster. looks around for darren
What you might consider doing is profiling the kernel on your test system

my general attitude is that when you are hitting 100% cpu
utilization, small performance improvements such as those
deriving from m_getcl() are not relevant, and you might
want to restructure your sw in order to get substantial
performance improvements.
In the specific case, at least reading

If you mean em(4) - I'd love to test them :-)

He probably can't tell because of the 32bit ifstats counters. They
wrap every other minute on a well loaded Gigabit card.
A 'systat -ip 1' shows rates ranging from 120kpps to 250kpps, averaging
around the 150 - 180 range.

i presume so, yes. I have some tweaks in the kernel to duplicate packets
in the kernel and get higher peak rates, but
