I tried to route the TTCP traffic via my NetBSD router

Linux <-> Router <-> NetBSD

and I get about 450 Mbps. Enabling HW checksumming does not increase the speed 
(okay, maybe 5 Mbps but not more).

Is there anything else I can tweak to improve the throughput when routing 
traffic between interfaces?
