Ah damn, I posted all, the results for eth2 are
774
63315
120652
75363
I also have a few vlans (but not on eth2), that's why there were more than twelve results.

few enough people use the cake stats in the first place and I agree the actual peak and a destructive read for peak would be better! @tohojo ?
are you just running that single instance of cake unlimited on eth2? If so, the only bql in still in use is the first one. I think.
(to be clear despite my original instructions, when I originally looked at that slice of data (with more than 4 results) I assumed it was a sampled stat, then I assumed cake was on eth0, not eth2, now I am assuming that I have brain damage from trying to absorb too many openwrt bugs and find common causes....
My connection stability is much better after applying the patch from link. I not I have a errors ... received unexpected tx_fetch_ind event: in push mode
error and ... failed to lookup txq for peer_id x tid x
... this way there is no blocked clients and no degradation of wifi (or I don't see it yet... ).
Some black magic bottom...

speedtest.net is not good a today ;), 15-20Mbps on RJ45 and about 15-18 wireless of 2.4GHz...
but was a days in this week when was it ethernet=wireless of 2.4GHz in near (to 45-46Mbps) and 18-24Mbps in far distance... Pings are better than without AQL patch but sometimes they still jump a little (but unfortunately my connection to Internet is LTE still...)
There are still bugs...

eth0 is left unchanged, eth1+2 both have a single cake instance. The Performance test always ran on eth2.
Hi,
@dtaht, I just compiled version v22.03.0-rc5 (Unifi NanoHD / mt76) removing two patches as per @nbd request:
334-mac80211-add-a-per-PHY-AQL-limit-to-improve-fairness.patch
335-mac80211-add-debugfs-file-to-display-per-phy-AQL-pen.patch
Same scenario, my devices are idle except this macOS (Silicon 2x2 MIMO), awdl0
down (to avoid periodic scanning):

** Note: in general with version 22.02.1 I get over 3,000 RPM easy. Latency, to my understanding, stills worse after removing the patches suggested by @nbd and running v22.03.0-rc5.
And this is it. @nbd, let me know if you need me to compile something else. @dtaht, any other suggestions?
Kind regards, and apologies for taking so long Real Life TM is very demanding lately.
LGTM +1
Looking forward to hearing back from @quarky (and others) that were experiencing latency issues either after about a 4+ day wait or intermittent latency spikes when certain devices disconnect from their AP. These make take time to report back.
thx all for jumping all over this today! I'm encouraged, and as I noted I'll settle for "stable" and "doesn't crash"! for now. Ship it, get it out the door, silence all the other bugs. Selfishly I'd like to take august off.
BUT:
It does really seem like we have something going not-so-well with download speeds, and that RPM result was poor. Not blaming this patch set and looking at other possible causes in patches elsewhere, the kernel upgrade, etc, seems sane.
@amteza A) would it be possible for you to repeat that rrul_be -l 300 result while also taking a packet capture? Ideally with ECN enabled:
sudo sysctl -w net.inet.tcp.disable_tcp_heuristics=1
An aircap is not needed, so that would be:
tcpdump -i your_interface -s 128 -w the_file.cap
B) a packet capture during a -l 60 --te=upload_streams=1 tcp_nup test
C) -l 60 --te=download_streams=1 tcp_ndown test
I don't trust osx very far and the long period latency swings you are seeing on panels 1 and 3, um... no. You can get at apple's internal fq_codel stats also, before and after the test.
netstat -I yourwifidevice -qq > somewhere.txt
The latest patch for mac80211 is looking good so far for my ath10k (21.02) and mt7622 (master) routers running it. No visible degradation of performance or latency from what I can remember with the pre-VTBA scheduler.
@dtaht, sure can.
See my /etc/sysctl.conf
:
@reaper$ ➜ ~ cat /etc/sysctl.conf
net.inet.tcp.ecn_initiate_out=1
net.inet.tcp.ecn_negotiate_in=1
net.inet.tcp.disable_tcp_heuristics=1
And, confirmation of it working:
@reaper$ ➜ ~ sysctl net.inet.tcp.ecn_initiate_out
net.inet.tcp.ecn_initiate_out: 1
@reaper$ ➜ ~ sysctl net.inet.tcp.ecn_negotiate_in

@amteza After long debugging, I finally got fping and flent working on the Macbook. I searched through Flent github issues and came across https://github.com/tohojo/flent/issues/240#issuecomment-931256026 . There's no fping6 command in macOS so I instead tried:
% fping -D -c 1 localhost
[1657503443.62438] localhost : [0], timed out (NaN avg, 100% loss)
localhost : xmt/rcv/%loss = 1/0/100%
Turns out macOS firewall has a Stealth Mode (System Preferences -> Security & Privacy -> Firewall -> Firewall Options... -> Enable Stealth Mode). That option was enabled. After disabling "Enable Stealth Mode" I confirmed fping to localhost is working:
% fping -D -c 1 localhost
[1657503635.17864] localhost : [0], 64 bytes, 0.116 ms (0.116 avg, 0% loss)
localhost : xmt/rcv/%loss = 1/1/0%, min/avg/max = 0.116/0.116/0.116
After that change, flent works.
@amteza - could you find it in your heart to repeat these tests and packet captures using 22.02.1 so we have a baseline?
@dtaht mumbai.starlink.taht.net is not working.

Grump. Try just ipv4, by adding -4 to your flent command line.
Still not working.

My apologies!! That was the old cluster that I had decommissioned. I have updated both the ipv4 and ipv6 addresses for mumbai to the new cluster, but it will take a while for the dns update to propagate.
You can direct your test at mumbai.v.taht.net for now.
Makes sense!!! I've got my macOS firewall always off at home. Thanks for the update. And interestingly enough my fping
just works, looks like I've got a little bit of luck.

Did you click the "Ok" button on the "Firewall Options" window after enabling "Enable Stealth Mode" ? The option doesn't take effect until you click "Ok".
in this test you seem to have your download sqm settings way too high for the perceived speed of this link (which looks like 16Mbit + whatever the cost of vnc), but please retry against my mumbai server.
