I did not see a significant improvement going from ppp(8)+9 and ipfw to = ppp(8) and pf+nat. Since ppp(8) already incurs the kernel/userland cost, = having it handle NAT on top does not increase latency. I've recently switched to mpd (and pf), and things "feel" snappier. I = haven't benchmarked it though, and my router box is rather oversized for = the task anyway (C2D). Friends using a Soekris swear that it helps a = lot though. The switchover is fairly painless, and the excellent mpd manual helps a = lot. Using one of the many examples, I managed to set up the mpd.conf = rather quickly; the only real adaptation was in the up and down scripts = I was using (my ISP kicks the connection every 24 hours, and I get a new = IP, so I like to bounce a couple of things when the connection comes up = again.)
