Emacs is generally slow about calculating animated images, and that
should be fixed (there's a separate bug report for that), but there's
one thing Emacs could be doing:

Not animating images that are off screen.

I think most web browsers do this -- to avoid using too much CPU, which
is the same problem we have in Emacs: Opening a web page with many large
animated GIFs usually makes Emacs very slow.
