I just got done tracing through a weird performance problem, which boils down to $SUBJECT. I have a pair of XT8s, one in AP mode connected to my wired net, one in media bridge mode. If I plug a device into the bridge's LAN1 port, I can get pretty nearly wire-speed iperf3 results to a server on the wired net: 910Mbps download, 920Mbps upload, zero retries. Plugging the same device into the bridge's WAN port, I get 477Mbps download (with 139 retries in a 10-second run), 920Mbps upload. What the heck? I'd think it was some compatibility problem between the XT8's 2.5G WAN port and my 2.5G Ugreen USB/ethernet dongle, except I get similarly awful results from a different 2.5G device plugged into the WAN port.
Anybody seen the like? Both XT8s are running firmware 388.22525. I don't think the wireless link is a factor: the bridge is reporting RSSI typically -42dBm and link rate usually 1801Mbps, and they are running in U-NII-4 spectrum (channel 169, 80MHz bandwidth) which I'm pretty sure is still reasonably-clear airspace in my neighborhood.
