I kept working on this issue today and went through my previous setup and results. It turns out that I had mixed my 21.02 and master results, leading to an incorrect observation. After cleaning up my mess and repeating my tests, I get roughly the same result for master (with DSA) as with 19.07.8. With an adequate number of parallel connections (eight seems to be a good number), I am able to reach 900Mbit/s-1Gbit/s. 21.02.1 peaks at around 500 Mbit/s. Since the only change between my sets of tests is the software, something has clearly improved in either the kernel or OpenWrt (as would be expected :)). Are there any particular commits/patches that would be worthwhile trying to backport to 21.02/5.4, or is the difference to master/5.10 so big that there is no point and the best is to wait for the next release? I guess one thing that hopefully shouldn't be too hard is be to combine 21.02 userspace with the 5.10 kernel. That will be on the top of my todo-list for tomorrow.
