Measured on the deployed console: the page shell and every module land in 39ms,
so the 1.4s was entirely /admin/api/ops/overview, fetched twice.
Twice because the sidebar and the overview view each called usePoll on the same
url, each with its own timer. usePoll now keeps one store per url, so any number
of subscribers share a single request and a single interval, and a request
already on the wire is joined rather than duplicated.
The endpoint itself was dominated by the jobs rollup: a full scan of
autonomy_jobs, 521k rows and growing about nine thousand a day. A covering index
on (job_type, lane, status, created_at) takes it from 548ms to 110ms.
