So anywhere I look for router performance on OpenBSD, all the benchmarks

are on small lines or old machines.  I also see mentions of people using

it in large scale installations, which is what I'm looking to do.  I

thought I'd ask here and see what people have done. 
I have 2 GigE lines from different providers balanced via BGP with full

routes from both providers.  Currently, these are running through a

Linux/Quagga/Iptables router/firewall with a P4 3.2 GHz.  The distro is

Gentoo, and we've stripped it down quite a bit.
We're pushing streaming video, so it's almost all outbound traffic by

about a 30:1 factor, and our average packet size is quite large - around

1200 bytes.  At the moment, when we hit about 350Mbps, the router gets

to ~30% CPU usage, and it appears that we stop being able to pass all

the traffic at full speed.  I don't see packet loss, but our traffic

graph flattens a good bit.  At those rates, we also start to see

crashing, but we haven't been able to figure out the exact cause of

those either. 
So, long story short, I need a new router.  We've looked at Cisco, etc.

and for what we're doing, it looks like we need a carrier class router.

I can get a decked out 12008 for about $8k, but I'd rather not spend

that much, or use the 2 feet of rack space.
I've used OpenBSD/PF for firewalls in the past, and loved them, so I'd

like to use it for a router if it can handle what we need.  Basically, I

need to be able to saturate both of those GigE lines.  I'm willing to

buy the brand-newest hardware - the PCI express bus should be able to do

2.5 Gbps, but I can't find anything that says I can push that much

through software.
I was also looking at the Intel I/O Accelerator, but I didn't see if

there was OpenBSD support for it.  I'm sure if there is, that would help

get me to be able to push the traffic I want to.
A long explanation, but I'm just hoping someone could give me some

insight here.
