Why is Lemmy so heavy on the CPU? (Firefox + Windows 10) (lemmy.ml)

Lemmy is the only website that causes my CPU fan to ramp up, other than games or heavy 3D stuff. Why is that?

Firefox on Windows 10 on Ryzen 5 5600X. It does seem to run better in Chrome. It's only noticeable when the page is loading.

Are you subscribed to a lot of communities and/or does it also happen when not logged in?

I suspect it might be related to loading a lot of community avatars which seem to not get properly cached in the browser or so.

I haven't really had time to properly investigate, but I also noticed it being a bit sluggy.

Maybe you best option is to try an alternative frontend like Photon or Alexandrite.
