20+ seconds to render the initial page content. 15 seconds of that spent fetching sub-megabyte JS files. This is impossibly slow and we should figure out why.

As it turns out, this required a change to the upstream chart:
https://gerrit.wikimedia.org/r/c/operations/deployment-charts/+/1005819
Anyway, with that change applied, the page loads from scratch in about 900ms for me, and also there's no more CPU throttling shown.
I'll send a PR upstream as well.
