dummynet & large traffic

[Evgeny A. Tyurnikov]

Hello All!

I try shape 1Gbit per sec to clients  ( /19 preffixes).
FreeBSD 8 Core i7 and two Intel 82572EI nic in bridge mode.
But more than 450 Mbit i do not see.

At the same time increases network latency on clients. I tune and freebsd and 
sysctl values, but the same effect. 

When turn in debugging, in /var/log/messages i see

....
