Re: Why is my gigabit ethernet so slow?

or so, to enable checksumming in hardware.

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?
