Please describe your issue in as much detail as possible:

My max download speed is something like 35mb
On windows 11, I can reach that no problem
On Linux, specifically Arch Linux right now, by default I was only able to get 3-4MB

I made a steam_dev.cfg file and put:
@nClientDownloadEnableHTTP2PlatformLinux 0
@fDownloadRateImprovementToAddAnotherConnection 1.0

This helped, now my download speed goes up to 14.5MB, still its only half as fast as it was on Windows
What is causing this?

Describe what you expected should happen and what did happen. Please link any large code pastes as a Github Gist

Steps for reproducing this issue:

1. Use Arch Linux (any linux?)
2. Try to download anything
3. Download speeds are much slower than Windows or other places
4. Using steam_dev.cfg @nClientDownloadEnableHTTP2PlatformLinux 0
   @fDownloadRateImprovementToAddAnotherConnection 1.0
5. improved it a bit, but still half as slow as it should be.
