Does Reddit site performance seem to be getting worse?

Hope it's appropriate to discuss here, but I apologize if it's not.

Does reddit site performance seem to be getting worse and nothing being done by the admins about it?

So reddit has infinite scroll and after scrolling through a few hundred posts and watching a few videos, my fans turn on and my computer starts putting out a lot of heat. I even left a reddit tab open on accident one night and woke up to my laptop too hot to even sit on my lap. Once the reddit tab was closed I could immediately hear my fans wind down.

I have a 8 core processor and 8 gb of RAM, shouldn't that be enough? Should any website need to be using resources the way reddit does? This has been happening for so long that at this point I would think some of the blame needs to be placed on the engineers that designed the site.

I think one obvious solution would be to remove content from the DOM after the user has scrolled past it. Does every video I watch stay in memory until I close the tab? No wonder the video player stops working after I watch a few videos.

I'm using Chrome on Fedora 36 btw.
