I'd recommend measuring some non-main-pages as well; that JavaScript
payload seems to be reduced by about half if you load some other random
page on Commons.
It looks like TimedMediaHandler is loading a lot to initialize a video that
might never get played, for instance, while it never gets loaded on a page
that doesn't include a video on it.

Commons currently loads more than 1MB of JavaScript. This is too much,
which negatively affects performance for our end users. Some of this
is on WMF -- JS code we've deployed that we can optimize. But it would
also be good to get community help with auditing site JS and gadgets
that are loaded by default and that can be reduced in complexity,
loaded only when needed, etc.
We'll aim to provide better debugging tools to the community in future
but wanted to point this out in case anyone already wants to take a
closer look.
