TomatoUSB

I'm using a WNR3500L v2 using the tomato-Netgear-3500Lv2-K26USB-1.28.RT-N5x—095-VPN.chk build and an all wired configuration (wireless disabled), and I'm seeing some throughput problems. Before installing this router I had roughly 400 Mb/s in, now I max out at around 108 Mb/s. When pulling 108 Mb/s for a prolonged amount of time, the CPU load on the router seems to vary between 1 and 3, so I think it might be CPU bound.

I'm not using any QoS or bandwidth limiting or anything like that. I've checked that all my interfaces are using 1000baseT. Everything is basically totally vanilla.

Is there any way to increase throughput and/or decrease CPU load on the router? I was hoping I could use it as an OpenVPN server as well, but this isn't looking too good at the moment.

run "top" command and look which one process will make that high CPU usage.

There are no proper processes that use any significant amount of CPU time, only the kernel (ksoftirqd). Here is a screenshot of top: i.imgur .com/CDz7Q.png (remove the space before .com. Sorry, can't post links yet.)

I noticed in the web interface (Advanced -> Miscellaneous) that only 10/100 Mb is listed for the WAN port speed. Is this just a legacy string or is it indicative of the capabilities of my WAN port? The WAN port supports gigabit, right?

(Double post, sorry. Tried to delete it, but apparently I'm not allowed!?)

Do the K24 builds work on WNR3500L v2?
