Description
When running
flent rrul -p all_scaled -l 60 -H netperf.bufferbloat.net -o mt76.png
Or equivalent to a local server wired into the lan the wifi performance is unusable. When on the 5GHz mt7612 radio on the same Netgear r6220 device the performance is much more consistent.
See last three images in https://forum.openwrt.org/t/how-to-write-a-meaningful-mt76-lag-bug/82515/19 for a sample.

Research direction
Reproduce the reported latency with flent rrul -p all_scaled -l 60 -H netperf.bufferbloat.net -o mt76.png, using either netperf.bufferbloat.net or a local wired server. Compare the MT7603E results with the 5GHz MT7612 radio and the sample images linked in the issue; progress requires identifying the cause of the unusable Wi-Fi performance and verifying an improvement.
