[Arm-netbook] Gigabit NIC Speeds

Hi All,

Not specifically Netbook, just a general question for opinions;

What is the bottleneck on arm devices when it comes to network speed?

I have a number of devices and they are all woefully slow. In order of poorness :) a few Dreamplugs (1/10th the speed of desktop) , a Cubietruck (1/5th the speed of desktop), a mirabox (haven't actuially timed it) et al.

Obviously there are many factors that can afect timings (depending on the test) but even using 3rd party Gigabit USB Nics the results do not improve. I've used netcat and scp (ouch) to name two methods, what would be a good leveller to eliminate outside factors?

Cheers,
