As agreed, here are iperf3 results, AP to STA distance is 2 meters.

Client sends, TCP:

[ ID] Interval Transfer Bitrate Retr
[ 5] 0.00-10.00 sec 70.4 MBytes 59.0 Mbits/sec 3800
sender
[ 5] 0.00-10.03 sec 70.0 MBytes 58.6 Mbits/sec
receiver

Client receives, TCP:

[ ID] Interval Transfer Bitrate Retr
[ 5] 0.00-10.06 sec 196 MBytes 163 Mbits/sec 3081
sender
[ 5] 0.00-10.01 sec 191 MBytes 160 Mbits/sec
receiver

Client sends, UDP, 128 streams:

[ ID] Interval Transfer Bitrate Jitter
Lost/Total Datagrams
[SUM] 0.00-10.00 sec 160 MBytes 134 Mbits/sec 0.000 ms 0/115894
(0%) sender
[SUM] 0.00-10.01 sec 160 MBytes 134 Mbits/sec 0.347 ms 0/115892
(0%) receiver

Client receives, UDP, 128 streams:

[ ID] Interval Transfer Bitrate Jitter
Lost/Total Datagrams
[SUM] 0.00-10.01 sec 119 MBytes 99.4 Mbits/sec 0.000 ms 0/85888
(0%) sender
[SUM] 0.00-10.00 sec 119 MBytes 99.5 Mbits/sec 0.877 ms 0/85888
(0%) receiver

Given the HW is not the most powerful, the key point here is that
nothing crashed after doing these tests.
