Flent rrul tests WLAN.HK.2.7.0.1-01744 and WLAN.HK.2.9.0.1-01890

Just a little follow up on this, and --bidir etc... I started to notice that my iPhone mini and Macbook Air with AX, had lower performance doing simple speedtests. It was very clear that the latency was all over the place doing a test compared to my MBP with AC.

Anyway, I'm posting some simple test results from a Macbook Air, when I have AX enabled vs disabled.

AX enabled  = HE40  (AX)
AX disabled = VHT40 (AC)

Note: This did not do anything in terms of performance.
option vht160 '0'
option short_gi_160 '0'

Below is speedtest results

Below is from waveform

And last, a little test with iperf3 --bidir to see if it improves with AC only (AX disabled). Hmm... that's better.

[ ID][Role] Interval           Transfer     Bitrate         Retr

[  7][TX-C]   0.00-10.03  sec   172 MBytes   144 Mbits/sec                  receiver
[  9][RX-C]   0.00-10.00  sec   169 MBytes   142 Mbits/sec    0             sender
[  9][RX-C]   0.00-10.03  sec   165 MBytes   138 Mbits/sec                  receiver

So there you go. Now I'm running AC mode, and just plain browsing feels quicker too.
To be clear. I have tested wlan.hk.2.6 up to 2.9 and no difference. I did test NSS for IPQ807x too but no improvement. The idea of testing this came from this thread:
