Windows 11 Network speed gets slower overtime.

I run OpenSpeedTest-Server in my LAN to run this Stress Test. (Full 1 Hour Continuous speed test)
Results should be 9400+ for Download and Upload,
I ran this test on Chrome and Edge on My Windows 11 Machine and observed the same issue.

I run this test on MacOS and Linux on Safari, Chrome and Edge. Everywhere I got 9400+ for upload and download. So this is a windows specific issue.
How to solve this issue?

Get OpenSpeedTest-Server to reproduce this issue,
OR
Docker Hub on a 10GbE network with Linux as Server.

The Windows operating system tends to go for a balance of performance and speed. There is very likely a different in network performance between operating systems.

If the speed difference is an issue for your needs then I'd run through this MS guide for performance tuning your nic.
