Dear Paul,
I still don't like the huge hit ipfw and lagg take :/
I think, you can't use fastforward with with lagg.

You have to try PF, then you will respect IPFW again ;)

So my maximum without polling is close to 800kpps but if I push that
it starts locking me from doing things, or
how many kpps do you

Andre, could you review this?
Yes, this should fix the problem. I haven't tested the patch though.
It works for me in the lab and on one production machine I patched
early this morning.

Hello,
I need to get SCTP congestion window data for research purpose. I collected
cwnd data from SCTP sender running on FreeBSD 7.0 machine by using KTR
kernel log. After that, I tried to plot cwnd vs. time and generated graph.
But I am unable to explain the graph and it is very different compared

When I started out it looked like 32 bit was worse than 64 bit, but it's
just the timers are different.
For instance, 4000 hz in 64 bit gives better results than 4000hz in 32 bit.
Low HZ gives better result with polling on in 32 bit
