I've measured the following so far:
Wired
speedtest: 850-950 mbps (my contracted speed is 750 mbps)
waveform/bufferbloat: 850-950 mbps, crappy bufferbloat rating due to my HFC upload on 4 upstream channels lagging the connection after around 65 mbps ( capping between 70-100 mbps).
CPU usage: 1-2% with hardware flow offloading enabled, 70-75% with just software flow offloading.
WiFi 5 GHz WED disabled (single antenna Redmi Note 11)
speedtest and waveform/bufferbloat: 100-205 mbps, consistent with my Archer C6 v2 after 5GHz Low performance on TP-Link Archer C6 V2 - #103 by Cthulhu88
note: hardware flow offloading was acting weird here and often giving me sub-100 mbps results, likely due to fw4 adding phy1-ap0 to the flowtable. devices = { lan2, lan3, lan4, phy1-ap0, wan } vs devices = { br-lan, wan } with just software flow offloading.
Next I will be trying the same phone with WED enabled and a 2x2 antenna laptop via iperf3.
