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.
