I have a netgear wndr3800 running OpenWRT aa rc1. The wndr3800 has gigabit ports but the most I can get through it with iperf is an average of around 80mbits/second (varying between 30 and 150).
Welcome to the world of teeny-weeny CPUs, mate. That CPU is not going to route that much traffic. Put the machines on the same VLAN and let the switching hardware do the work. It probably shouldn’t be advertised as gigabit unless it has enough CPU grunt to route — not just switch — at a reasonable speed. The NetComm NP805n can route PPPoE at around 450 Mbit/s (tested with iperf and a MikroTik PPPoE server), which is pretty impressive. Now for someone to port OpenWrt to it... I have a friend who bought a “gigabit” NAS (Western Digital MyBook World) which couldn’t even do 100 Mbit/s of SMB traffic. Mind you, with her Windows XP client machine using only a fixed 16 KB buffer by default (without tweaking the registry — oh gosh, SMBv1 is *fun* over high-latency WAN links) the box was kind of set up for failure...
