Possibly. I really did not bother to investigate, but a simple A/B test of ipchains 
vs. iptables shows poor TCP performance when using a 2.4 kernel. I should probably do 
more tests, but lack motivation since the problem is solved, as far as I can tell. I 
am migrating the entire system to Debian because I am no longer happy with RH's 
releases so I'll be able to do more tests sometime next week.
