Huh? .. the FWSM (which is PIX and you can have 4 of them in a chassis)
can handle 100 intefaces, 5gpbs, 100k CPS, and 1M concurrent per blade.

Show me an OpenBSD system that can handle 400 interfaces, 20gbps, and 4M
connections (and can do HSRP, etc).

(I'm not trying to start an open-source "holy war" on a newsgrop .. I
use pf too, where I need the granularity -- just not on the whole network).

I suspect the argument here has to be cost-for-cost - in the price range for a 
decent beefy OpenBSD box you aren't going to be using FWSMs, and I can quite 
believe that the PIXen in that price range don't perform - the PIX 501 is 
specced at 60MB/s throughput and the cheapest retail price I can find for it 
is $678 for the unlimited license version - for the same money you can get a 
beefy PC which will push quite a bit more than 60MB/s

FWSMs appear to retail around $23,000 - that's on top of the 6500 chassis and 
line cards you need to use it - not exactly a fair comparison.

For that money you could quite easily put together a farm of boxes that would 
exceed 5GB/s throughput aggregate - whether you'd want to is a different 
question.
