Ok Download / Slow upload

[PotatoVeggie 1]

Greetings!

Despite tweaking buffers, MTUs and other things, I am unable to get upload speeds above ~550+/-50 Mibps on a server that should have enough capacity for at least 10Gbit more. 

Is it possible to achieve 8-10Gbit upload speeds on servers that report available capacity for it? If yes, please share config changes that I need to make in order to fully utilize my connection.

What application are you using the VPN with? Also, what is the max upload speed you can currently get? (Just curious I'm not sure if I will be able to help)

I am using a vast variety of applications, so any I will appreciate any and all guidance that will allow me to unlock full server capacity.

This guide helped me a lot for my use case: https://github.com/felikcat/seedbox-tutorial, you can check the sysctl config. For the connection, I am using Gluetun with WireGuard. I hope this helps you!
