Some topic-related observations:
AMD Athlon XP1700+ (1466), 4xRealtek8139, 5-6Mbit/s - nearly reaching the limit
of machine capabalities
P4 2000, 3com905C+BROADCOM BCM5701, 40-50Mbit/s - far better behavior
Same configuration on both, thousands of iptables rules, and on the p4 machine
there are 200-250 concurrent pppoe sessions (none on the athlon)
