Max speeds are not accurate in list of supported routers

[jphein]

With the current firmware release I'm only getting ~80mbps one way max for the mr8300, ~70mbps for the ea6350v3, and ~70mbps for the er-x.
They are marked as 250mbps, 200mbps, and 150mbps respectively.
I've tested with iperf3 one way, fast.com, and speedtest.net. Can we come up with a standardized test? I like the iperf3 --bidir flag, because it tests upload, and download simultaneously.

I'm hoping we will get better speeds when we start using openwrt 22. In my testing it's much faster than openwrt 21.
