As I don't use group/head right now maybe I'll give that a try.  I also
forgot to mention that I have about 28 "count" rules which I use to get
various stats (bandwidth, state, packet) and graph them with mrtg.  Could
they be slowing me down somehow?

Odd.  I have a bunch of similar systems (p3-550's, 256mb, dual fxps,
bridging, on obsd2.9) .   I use head/group, with ~30 heads.
I don't pass ICMP (other than PMTU), and they don't get upset and start
bogging down until about 45-50Mb/sec on diverse http traffic at a churn of
~6000 states/sec.

I wouldn't expect your ruleset size to make that much difference, but
who knows.  According to all the other datapoints given, your firewall
should be totally idle.   Perhaps it's getting bored? ;)
