[Bug]: Why is the speed several times lower on Windows?

[SheerGeyser]

Application

Outline Client

Describe the bug

ubuntu 22.04:

windows 10:

Steps to reproduce

1. Open Client
2. Connect to VPN
3. Check speed on SpeedTest

What did you expect to happen?

I would like to achieve the same speed on Windows as on Ubuntu

P.S: I tried changing the metric of the adapters to quickly determine DNS, the speed does not change at any value
I would like to add that the provider and the same network are the same, the maximum allowable speed without VPN is 500 Mbit/s.

I checked with friends from other cities on a PC, they have an identical situation, the speed on Windows is several times lower

What actually happened?
