So this one is basically the same platform as Linksys WRT1900AC series?
same SOC yes - but different connectivity - more flexibility

It's lucky that you didn't post it a week earlier, was super busy with my work and I didn't have much time to update 
This is interesting, initially I did that on some of my devices and almost no difference with irqbalance/packet steering at all
I don't fully understand the scripts. If I have an existing wg interface already setup (wg0 for me), what are the commands I can run manually to mimic the benchmark?
I recommend you to ask the author using the GitHub link I provided, but I don't think it's a good idea to use something already in production to test with??
Boot Openwrt off a flashdrive, instead of messing with a working environment.
But this way doesn't work for normal home routers, only suitable for x86, or SBCs
indeed, I (incorrectly ?) assumed @darksky was using x86.
I am using x86/64
