GL-MT3000 - poor network performance

hello, and thanks for taking the time to read this topic.

i am long time user of gl-inet products
— microrouter usb stick
— ar750s-ext

in the past, for 5+ years, at work, i run opnsense on a 8+ year old computer.

now, i just purchased the gl-mt3000 and its performance seems much worse.
my internet connection is verizon fios, 5 static ip, max upload is approx. 40MiB/s

the issue is not upload speeds, are both routers can saturate the internet connection.
the issue is latency.

i am very confused about these results, is the gl-mt3000 doing something extra to produce the poor results?


as an example, i run rclone to upload a .iso to idrive e2.
using that 8+ year old computer, the latency is consistently the same as if i were not uploading at all.

where as, with the gl-mt3000, the latency increases are in direct proportion to upload speed.

using rclone with --bw-limit=10M, the latency is close the same as not uploading
using rclone with --bw-limit=20M, the latency increases to

using rclone without bw-limit, the latency increases to

i did some more testing, paying attention to the cpu and memory usages.
from htop, each second the cpu usage changes but not more approx. 20%

i am correct, that my issue is not related to cpu usage or lack of memory?
if correct, then what is causing my issue?

Hi

Could you try enabling SQM by following the guide below and see whether it improves the situation?

Before configuring SQM, we recommend

  1. running a Speedtest to measure your actual Internet bandwidth.
  2. For the initial configuration, set the upload and download limits to approximately 95% of your measured bandwidth and run a bufferbloat testing to see whether getting a good result or not.
  3. If the results are still not satisfactory, you can gradually reduce the values further, for example to 92% or 90%, and test again.

sure, i will try it.


from the docs “On the left side of the web Admin Panel, go to FLOW CONTROL -> SQM.”
from the docs, ※GL-MT3000 (Beryl AX) Note: Models marked with ※ support SQM in firmware v4.9 and later

i cannot find it in the admin panel?? please advice, thanks much, david

the router is running v4.8.1

Go to Application > Plug-ins, search up luci-app-sqm and install it, then go to System > Advanced Setting > LuCI, then go to Network, click dropdown, you can find “SQM QoS”
