CAKE is very processor intensive, more so thanย fq_codel.
I seem to remember a conversation with ASUS I had that the Broadcom chipsets support a type of Symmetric multiprocessing., so some offloading will happen
My CPU Core 1 hit 85% whilst downloading a large file from the internet.

Update time.
So I decided to do some experimenting. Amazon had the RT-AX86U Pro on offer for ยฃ210. The same price I paid for the DSL-AX82U.
I decided to get it. Instead of the CPU going to ~57% I am currently not seeing a CPU load over 25% with the exact same Cake settings on the Pro. Basically it’s ~50% more efficient. I was satisfied with the DSL-AX82U but I thought to myself if I get even the slowest FTTP package at BT (150Mbps) the DSL-AX82U is going to choke. Now if I run Cake at ~138 Mbps I will not have any CPU limitation issues. No way is the DSL-AX82U shaping that much bandwidth.
Unfortunately the rate limit thing with torrent/blizzard is still there but that does rule out alot of issues in that it’s probably something to do with QoS in general. In fact the non Cake QoS also suffer from this problem (adaptive and traditional) but to a slightly worse extent so I can’t really blame Cake directly. It must be how some limiters are configured.

3 things to note.
1: I think I found a really quick and dirty way to find out mpu to back up previous info. For some reason if you ping the Google DNS with specific flags it will tell you what the mpu is.
e.g.: ping -f -l 1464 8.8.8.8
This is on stock Asus firmware and no QoS. I only noticed this when I got another ping screenshot from someone on Tp-link device and noted the same 68 number.
2: Can you confirm the above? If at all possible do you then know someone on BT FTTP or similar to run the command and see what number they get? It would help me work out some theory.
3: Are there any “optimal” configurations for wireless range on these Asus routers? I have everything default and the range seems pretty strong that I can’t really complain but just wondering.

Nice little find that is, I have a Fritz!Box (modem / router) plugged in currently (long story) but ran the ping -f -l 1464 8.8.8.8 and MPU value seems to hold steady with your original maths (68)
I will plug in the Netgear XR500 early next week and try the ping -f -l 1464 8.8.8.8 cmd also to see if MPU value drops by 4
Hopefully somebody on a FTTP connection can help test the ping -f -l 1464 8.8.8.8 CMD for the full fibre connection in UK

Forgot to mention adjusting Antenna positioning as below, should help.

So I plugged in this morning my DrayTeK Vigor 130 modem and connected the Netgear XR500 to the Vigor 130 modem and ran the ping -f -l 1464 8.8.8.8 CMD
Like previous, MPU value was also 68

That’s good to know.
I had my very first issue with this Asus router. Maybe it’s been happening for awhile without me knowing it but I needed to print something and it simply refused to print (brother printer).
It was connected to the network via wi-fi and I could see it on router.asus.com (as did the wifi light state it was connected on the printer itself). My desktop could ping the router itself fine (192.168.50.1) but any ping to the printer simply failed. I tried restarting the pc and the printer but same problem. The only fix was to switch the Asus router on and off again.
