Why does Chess.com use so much RAM?

I play Chess on my school computer which has 4 gbs of RAM. When I use Chess.com the site uses 2-3 gb of RAM which causes the site to be slow. I believe using this much RAM is absurd.

try disabling engine evaluation in settings

also disable chesstv and analysis after game (because it runs stockfish in your browser locally)

I noticed that too... Chess.com in my Xbox browser keeps saying "memory exceeded" when eval is on. Limited RAM may cause bots to play below their given ratings. The other chess website doesn't have these problems (to this extent).

I have often experienced the problem of all memory being used but I have an old computer. I think it happens when I have multiple windows open and one of them is running an analysis.

To play fair speed chess on this site you must close the game screen after each game. That resets the page RAM usage to approx. 400 MBytes. If you fail to remember to do that the page's RAM gradually grows after each game you play on that board. About 3 games without reloading the page gets the page's use to 700 MB. After 12 games it goes to 1GigaByte. after a few dozen games it will pass 1.4 GB going up to 4 GB. Somewhere along that ramping a modest computer like my MacBook Air runs the graphics in slow motion, and the sound effects occur several seconds after the pieces move on the screen. A couple of games after those punishments reduce the games to essentially nonsense, the screen goes black with the words "Ah, Snap: something went wrong" and you have lost that last game and must reload chess.com anyway to be allowed by them to play further chess. I've gone through that a few hundred times, and most other people's posts about this subject match my exact RAM increase measurements. One poster said "but chess.com is the only site in town so we're forced to deal with whatever they do to their chess board pages". As far as I know that statement is correct. But as I said, reloading the chess board page after each game completely solves those RAM problems, and its not that time consuming a task to have to do, and I guess chess.com doesn't punish players who do that (maybe).
