### Region

Norway

### Provide a description that is worded well enough to be understood

For some time now I have had reduced downloading speeds on Rumble. When the download begins the speed is several MB/s, but it very quickly reduces to 300-400 KiB/s.

When similar throttling has happened on Youtube this has been fixed in consequent yt-dlp releases, so I wonder if perhaps this issue on Rumble hasn't been identified.

The session quoted below started out >2.5 MB/s

### Provide verbose output that clearly demonstrates the problem

- [X] Run **your** yt-dlp command with **-vU** flag added (`yt-dlp -vU <your command line>`)
- [X] If using API, add `'verbose': True` to `YoutubeDL` params instead
- [X] Copy the WHOLE output (starting with `[debug] Command-line config`) and insert it below
