CakeQOS GT-AX11000 with 1.5gbit symmetrical fibre internet and QoS

[dusan78]

Hello,

I am searching for some answers regarding using cake QoS on a Fibre 1.5gbit symmetrical connection which I just got. I am using a AX11000 router. Without it I am getting 1gbit download and 1.4gbit upload using the speedtest on the merlin router GUI. Running the test on multiple devices I can pretty much get 1.3-1.5gbit bandwidth combined. However my issue was testing the waveform bufferbloat adds latency under load and I get B or worse grade at the moment.

Enabling cake QoS reduces my speeds all the way down to 500 upload and download and whats worse is that if I run tests on multiple devices, I am getting 500mbit max combined so on two devices the speed would split to 250mbit each and so on. However, the bufferbloat is now much better at A or A+.

This mirrors someone elses experience on this forum but, I also read someone else getting 1gbit with it enabled. So is this something I am not setting correctly or is the limit of cake really at 500mbit and with faster connections should be disabled or other QoS service used. Any advice would be greatly appreciated as to how to get best latency as well as bandwidth possible for my setup.

Thank you!

IMO, Cake is not necessary for 1.5 Gbps symmetrical connection. Consumer routers cannot handle the processing overhead.

Thank you, is there any other QoS that would work to reduce the latency I am getting under load.

Same as you, have 1.5gbps with gt-ax6000. For my Bell ISP, Have used QoS and disabled it as i have noticed that your weakest link is websites, torrents, steam(max. 400mbps for me) games, etc.

Besides, QoS will only be triggered when you hit max 1.5 ~ 1.3gbps(depending how you setup.) and even for multiple heavy users for me it was never activated. As always, YMMV.

Don't waste your time with this website.

(That waveform test is debated by people as to its accuracy...)
Symmetrical 1.5Gbps is a pretty healthy connection to be maxxing out in a typical home environment, and your router is a rather capable machine to be managing it. I would suggest that you might consider looking into network segmentation (vLANs and Subnetting) rather than QoS.; let your ISP do the speed control - if you manage your traffic onto their highway, chances are they won't slow you down

 

[dusan78]

To give an update as I have solved my problem with latency. I played around with adapter settings where I disabled "throughput booster" and I also disabled "autotunninglevel" as per someone else's advice from another thread. These two completely eliminated any latency but, I did have to trade in some maximum single connection speed. If I was copying a large amount of data over the network I would turn this back on but for everyday use it's perfect.

I have upgraded my service to Fiber 1gb symmetrical. I normally use Cake QoS and noticed only getting about 350-375 Mbps speeds. If I disable QoS altogether, I get 900+ Mbps. Does that mean the Qos on the router cannot support my speeds?

Also, sorry for noob question.. do I even need or benefit by using QoS with 1gb connection?
I was using QoS before since I only had a max of 50 Mbps.

You are lucky to get 500 max. You are hitting the routers CPU max. Cake relies heavily on the CPU of the router. On an RT-AX88U-Pro, I was only able to get roughly 360mbps with Cake. It is the limitation of that routers CPU. With Firewalla Gold Plus and cake qos, I am hitting my speeds. As you can tell, I don't exactly have symmetric connections:

Hence why I say CPU is your limiting factor.

In my experience with similar, your hardware is just not meant for those speeds. If you are saturating the line with say, maximum downloading or torrentlng, then you would need it or you need to limit the bandwidth on your PC. But, for regular internet use its not really necessary at that speed. What was also slowing my connection down was enabling app monitoring and whatever other packet analyser is running on the router. I disabled all of that and everything is perfect now.

The only reason I use cake is to cap my upload which is not a symmetric match to my download. I agree with your statements 100%.

This model Firewalla is a mini PC with Intel N97 CPU. Will run circles around home AIO routers.

I agree, but it was to illustrate a point about the limitation of the routers CPU.

If it's one PC or server that is uploading the most you can also try using Netlimiter on it. You can even control per app bandwidth allocation in both directions. It a paid software but, has a free trial. Will also give you a nice breakdown of all the apps and services receiving and transmitting.

Anything incompatible with NAT acceleration will result in WAN-LAN reduced speed limited by the CPU processing capabilities.

 

[SomeWhereOverTheRainBow]

Therefore, if possible, I would only cap the upload speed; however, a symmetric connection above 1gbps should not need any cap at all. Welcome to the world of faster connections and updated wiring; in this instance, rely solely on that NAT acceleration of the router.

 

[fotingo]

Thanks guys. I will keep QoS disabled then and see how it goes. Happy with new speeds. This is my first time with anything higher than 50 Mbps on my router lol.

 

[Tech9]

Not sure if this is possible on Asus routers. The moment you cap something with Bandwidth Limiter, Traditional or Cake QoS - you cap the entire network behind the router. On your Firewalla there is no NAT acceleration and the software is different. My UCG-Ultra is similar, but with ARM CPU.

If you have any latency, or gaming issues with no QoS or streaming, perhaps there are other things you can change to resolve the issue.

eitherway, it is a mute point if you have a 1gbps connection symmetric or above. My connection is Asymmetric. His upload and download are the same, mine is 2000mbps+ on the download, and only 40mbps on the upload. Firewalla software allows separation of the download and upload packets when using cake.
