Problem is that I am using 1Gbps broadband at home, doesn't make sense to spend 425USD just for a router which could route 1Gbps NAT traffic, I believe I could get something like TP-Link at half of the price (or less)

for benchmark, I use http://www.speedtest.net to do testing.

I am running simple broadband NAT, my goal is to reach 1Gbps for NAT routing, looks like I bought wrong model to do NAT routing.

And yes, I could only reach 300Mbps max and at that traffic, CPU jump up 100%!

I just got my first RouterBoard which is 951G-2HnD, did some testing and max sped is 300Mbps; Is this board too slow for 1Gbps connection? or there is some misconfiguration I have done on this board?
