I wish I knew actual numbers, but I know that I had two net4801's as
endpoints of an IPsec tunnel, each on 1.5 Mbit/s lines running OpenBSD
3.5 or 3.6. Someone started pushing a big file across the line, and
suddenly one of the routers dropped off the internet because it had no
CPU left after trying to handle all the encrypting and decrypting.
Again, I don't know how much traffic that really amounted to --
however fast two boxes can go across good 1.5 Mbit lines and 40 miles
of southern California. Turning on altq and capping the bandwidth
available to that tunnel fixed the problem (though it made some users
unhappy when they couldn't transfer their files as quickly). All that
being said, we 1) didn't have an encryption accelerator in the box and
2) didn't really spend any time doing performance tuning on it, so
someone who worked at it could probably get more out of it.
