I can plug back in my DSL-AX82U next week, currently have my Netgear XR500 in for my Son’s gaming over the weekend etc.
What are you looking at in particular from my testing and a schedule would be handy ?
(P.S. I did mention earlier, QoS is aย hugeย subject)ย

No rush on it, thanks. I think basic test would be something like have cake installed on latest gnuton then:
1: Run waveform test with nothing active to make sure latency and jitter is fine.
2: Set something to download at around 60% of your total bandwidth. Helps if it’s like 10GB+ so you have time to test.
3: Run waveform again and check latency/jitter.
Ideally step 3 waveform should show all ticks even for low latency gaming.

No problem, will give it a go with CAKE QoS

You weren’t kidding about QoS being a complex subject. Another deep hole emerges…
I just decided to try downloading a Linux ISO from here in Chrome: https://ubuntu.com/download/desktop
This was with 0 throttling or anything: https://www.waveform.com/tools/bufferbloat?test-id=5276cd72-fed1-413d-80ac-bc630a04784e
Wtf… explain that. I then thought to myself maybe something is wrong with the Blizzard launcher downloader. So now I left blizzard completely unthrottled: https://www.waveform.com/tools/bufferbloat?test-id=365a5fff-e53e-46f2-b505-3deddb1f3e52
I don’t know how I failed low latency. Everything looks fine. I can only assume that the download speed is too slow to get the tick? Jitter looks more than adequate now.
Now I did what I did before… I set blizzard launcher to 20Mbps limit: https://www.waveform.com/tools/bufferbloat?test-id=7b47acc8-eede-4d03-9252-4dfb6ef4ed4d
The jitter issue came back. Now I set it to 10Mbps limit: https://www.waveform.com/tools/bufferbloat?test-id=53f75547-42bc-4708-98a1-22cfeb304b79
I got the low latency tick on the left, backs up the theory it’s about download speed. I still got the increased jitter issue.
So if I understand this correctly… you should not actually use a rate limiter on any type of traffic. It just leads to worse performance… I don’t know how but take it as you get it I guess.
Edit: Yip just checked waveform FAQ section. I did not get the tick because I was less than 10 Mbps (was at 8.31 Mbps):
So if I don’t limit anything it seems… fixed. I would still be very curious to see your results.

Yeah that’s running as expected so far. Can you run a rate limited download in say qbittorrent (set it to max 20Mbps or so) and then run another waveform as it downloads? Blizzard download also a good test:

It’s actually pretty ridiuclous that browsers don’t have easy bandwidh controls for stuff like this.
The easiest thing to do would be get a linux fedora torrent: https://torrent.fedoraproject.org/
The top torrent works fine and should easily do what is needed (Fedora Astronomy_KDE Live x86_64 37). It’s 4.5GB so enough time to test.
In qbittorrent go to Tools > Options > Speed
Then run waveform.

I will see if I can get chrome rate limit to work my end but even if not it doesn’t matter. Just gonna run everything non rate limited anyway.
I do actually wonder how much throughput this router can do under cake though and still be reliable. On my connection I’m seeing peaks around 50-60% on core 1 (the core actually doing the cake stuff).
If you have around 70 Mbps dowload once shaped via cake, how is your cpu peaks? I’m guessing around 80%?
