I tried this.. I put 6-STABLE (6.3), using default driver was slower
than FBSD7
I tried yandex driver 1.36 and it was even worse.. It would make the
machine unresponsive and drop more packets than the default driver.
It would make 'top' show cpu's were 300% idle and a command such as 'w'
would take 5 minutes to respond so obviously something is wrong with
this driver :/
In the em taskq does it do all the routing also? Can the received
packets be accepted with em0 taskq and dumped into another multi
threaded thing which will do the routing and send it to the output taskq?

Dear Paul,
Yes it does but it seems to use a lot more of one cpu than the
others so It's really not SMP.. Can I stop it from doing this with
some setting?
Why can't there be 4 taskq's?
it is possible, but it need to be coded.
hz 4000 is also too high, use 1000-2000

Those are very old test results using a fairly different em driver
than whats in the tree.
You might look at

on RELENG_6. I havent tested it, but supposedly its optimized for
forwarding on SMP hardware
