QoS issues (again)

Thanks for the screenshot. Never doubted that it works for you. It is just that for some reason it does not work for me..

And after a few tests, I believe there is a possibility that it would not work for you, either, if your speed was above the one you have.

What I mean:

I performed a first test using your numbers. (Total 32500, guaranteed 30000, limit 31000)

The results I get are similar to yours .. I got 204/44 - forgot to take a screenshot :)

I then cut the numbers in half (Total 16000, guaranteed 15000, limit 15500).  Run a speedtest and download speed indeed was cut in half

I then set the numbers at a quarter of yours (Total 8000, guaranteed 7500, limit 7800). Run a speedtest and again the speeds are cut at a quarter of your speeds.

So everything from about 250Mbits and below works as expected so far. I then set once again the speeds at about double your numbers. (Total 60000, guaranteed 58000, limit 59000)

And lo and behold, the speeds are not exceeding your numbers

I am starting to believe that there is a bug and it won't let speeds go above about 250Mbits.

And it is just a diabolical coincidence that your speeds don't exceed 250, so you have never experienced this issue.

But of course this is purely hypothetical. I hope there is someone with speeds above 400 that can run a test (??)

I previously had a 1000/50 link which maxed out the xg115w at around 600-700.

Don't know then...

Can't be sure. I can't understand why I am the only one having this issue.

Is there perhaps any bug introduced lately that is causing that behavior?

If there is anyone with the latest version kind enough to test with a connection faster than 400 Mbits, it would be great.

At least I will be sure that the problem is only on my side (although I can't comprehend why this would happen only to me...)

Do you have ips enabled on the testing rule p, if so what are the settings?

I did not even have a rule in place during the above tests.

But just to make sure I enabled the rule now and got same exact results as the last speedtest screenshot (about 250down)

The rule has no ips configured. It is just a simple rule. Source zones all my internal networks, destination zone WAN and from the rest of the settings I have nothing configured, no app control, no web filter, no ips, just trafiic shaping:

The Home_QoS rule has the below settings:

Perhaps it is worth mentioning that if I change Upload bandwidth to half of the above (3300), the upload speed is limited to half, as it should

So once again the "low" numbers work as they should.

Numbers that offer a download limit above 250Mbits are the ones that don't work

OK, here is mine

Additionally let me share that for download speed in the traffic shaping rule, even if I put the max number 2560000, it still limits to 250Mbits 

It is as if it will discard any number above 30000-35000 for download limit

A suggestion you might like to consider, your hardware is being maxed out. You could try running two or three speed tests at the same time from different devices and look at the diagnostic graphs.

It has crossed my mind and now that you mentioned it, too, I gave it a try

I run a windows app speedtest and a command line speedtest at the same time. During these tests I had the XG console running top.

The tests combined did not exceed  280Mbits down while CPU usage did not exceed 58%.

EDIT : Run again and CPU reached 72%. With only one test running it does not go beyond 60%

Are there any other commands I can issue from the console to possibly get more accurate readings?

The cpu is a 4 core so unless you go into console and run top or similar you will never see what is happening.

i did a deeper investigation into the cou, it is 11 years old model with in built nics, so probably you are seeing the best performance you will get.
