Yep. Most performance-oriented thing I've done with OpenBSD was
firewalling a 45Mbps T3 line. It did tax the machine a little bit,
but the primary firewall was a Celeron 600, about five years old at
the time it was put into service (failover was a PIII-750, which
showed a lot lower load, I think it was more the cache than the MHz).
Lame. :)
