I don't see why throttling should happen somewhere in the chain. Should be roughly the same as for Pi3B+ with a Gbit PHY connected to USB2. So roughly 300Mbps, half duplex in HW. At least less than 480*(8/10), but less SW (and HW) protocol overhead.The Ethernet gadget feels like 100 mbit to me.Does anyone have any data (or reasonable back of the envelope estimates) as to the relative speed of a Zero2W as an ethernet gadget - plugged into a modern Mac via a 5gbps hub - versus its own wifi? I realize the Zero2W's own usb is probably the limiting factor, not the host's; I'm mentioning the host side in order to take it off the table as a limiting factor.
Although interesting use-case w.r.t. high speed, it is only max 5meter cable length. That is basically why I never tested it (for fun) on Pi4 (I don't have Pi02W). Pi0 might hit CPU performance limit. I do not know either, but speed with Gbit USB ethernet adapter was well below 100Mbps AFAIR, but that might be because I never looked at the the link speed which might have been simply FastEhternet (100Mbps).
Wifi is limited by SDIO speed. Do not know that SDIO limit, I always use 20MHz channels, then speed is roughly 50Mbps max.
