Yes, the interrupts are the core issue - me a while ago: http://article.gmane.org/gmane.comp.security.firewalls.pfsense.support/1334 I replaced those [rather new] RTL NICs with some cheap old e100/FXP/Intel ones, and dropped my utilization down to single digits. If 5Mb is all you need and you can get that while preventing the lockup, then go for it. I'll never buy another Realtek chipset again.
