How loaded is the Alma Linux server?
What are its specs for CPU / RAM?
Is it hardware-based or virtualized? If virtualized, what is the
Are you as a client in the same location or different locations?
Any traffic shaping configured somewhere in between the server and the client??

my current network speed test

i am using this wireguard client for windows 10 https://download.wireguard.com/windows-client/wireguard-installer.exe

[Rebelllious]
