Safari acceleration (experimental features)

Hi, is there any way to speed up safari?

When I have a lot of bookmarks on the main screen, a new tab (and in general moving through the tabs is delayed, and scrolling through the list of bookmarks looks like it's freezing).

I moved all my bookmarks to a folder and now a new tab is created much faster.

Also, when I scroll sharply up on YouTube for example, I first see a white screen and then the content appears (I don't remember this on Catalina).

Is there anything I can poke around in the experimental functions?

The only thing I've enabled so far is WebGL via Metal (because without this feature and me in google maps artifacts)
