Speed throttling ?

You might ask in the Comcast ng.

I see data usage defined here:

I am getting 300 Mbps at most sites.

At youtube, I get 20 Mbps.

The assumption is that at YT you're streaming, not downloading, so 300 Mbps would be completely inappropriate. Normally, when you watch a YT video, the video quality is automatically selected for you but you can try to manually select a better stream and see what happens. Probably nothing will happen, because YT's streaming algo automatically adjusts the bandwidth for you.

If you're not streaming from YT, tell us what you're doing instead.

I don't know if I am streaming from YT.

I just thought I was downloading.

When I watch a YT video is is streaming as it downloads just enough to keep the action moving but it is not saved to the computer. Yes, there may be a temp file for buffer but it goes away when you are done with that video.

Downloading is more like a spreadsheet or PDF saved to the computer for future use.

There is a YT down loader site where you can download and save but either viewing or down loading or both I would consider part of the data usage.

I do not see how you can determine download speed is different at YT. I logged in there and watched a video and my speed test app appears to be normal.

Youtube doesn't offer download capabilities[*]. The various youtube downloaders simply stream the video/audio to a file instead of the graphics adapter. The download speed is min(ISP speed, YT stream speed).

I know. Been awhile but I used this site to download a few old movies:

Exactly right. When you click on a video and watch it in real time, it's streaming. Youtube does allow its videos to be downloaded, but the default is streaming and, as you said, the data stream only needs to be fast enough to keep the video buffer suitably full.

A relatively new option at Youtube is Youtube Premium, which for a fee allows you to download any video at full speed and it removes all ads, even when you're just streaming.

Youtube used to allow downloading of any of its videos by placing a download button with the other buttons along the bottom of the video. A number of years ago, they removed the download buttons and as a result,

There have been recent reports stating that youtube videos no longer download at full speed, but so far I haven't found that to be the case. For years I used yt-dl.exe but development seems to have ceased so I've switched over to yt-dlp.exe, a fork of the original project. For me, youtube videos still download at full speed (and without ads), but the best thing is that these downloaders work at hundreds of video sites.

I have an app that shows DL speeds. Speeds are around 300 Mbps on other sites but 20 Mbps when downloading audio or visual.

You can do that with youtube-dl or clip grab.
