Can squeeze out 120Gbit/sec using multiple threads.

Completely pointless benchmark of course.

Would it make sense to post a measurement about a device that was measured above already?

178

Not really, unless there's a huge difference in performance.

179

…and the whole exercise remains to be totally bogus and useless anyways, given that this merely tests the memory bandwidth, which doesn't allow any conclusion about routing- or wireless performance (at all).

180

So what, it's kinda cool anyway

Could someone with a device that tested well below 1gbit run another test from a wired gigabit client connecting to iperf3 on the router? I'd like to know if the results are higher. I suspect 2x higher is possible.

182

Perhaps coremark results to compile a performance metric of fastest single core on a SoC would be more useful?
