The tests were performed as follows: start a 5 minute 12 stream TCP downl= oad on my laptop, and about halfway through start a 1 minute iperf3 downloa= d on my smartphone. I did this to test what happens when multiple stations = simultaneously run downloads. The result was that throughput of the flent t= est dropped very low and latency climbed way above what it was prior to sta= rting the iperf3 download. The results can be seen in this forum post: http= s://forum.openwrt.org/t/aql-and-the-ath10k-is-lovely/59002/200?u=3Dhuarache= guarache Does anybody know what the reason for this behaviour is? Michael
