#241: on production, All Subscriptions' query runs in 31 ms, unread oldest-first in 30, the feed list's count in 5, generic plans included (EXPLAIN ANALYZE, BUFFERS, read only), against 0.3-1.6 s in ipx. A new Postgres connection takes 80-330 ms to open, and a page load asks for more than are idle: four of six slow loads came as the pool grew (3 to 6, 2 to 6, 3 to 5, 6 to 8), and 20 requests at once took a median 414 ms while the pool grew from 8 to 20. The daemon and the directory's server now keep their whole pool open (min = max); a command such as `ipx status`, and the tests, which share the server's 100 connections, open as they need. #246: the page reports list_shown, the ms from asking for a list to drawing it, with the view and filter, under the click's trace; background refreshes are not timed. Timings skip report()'s once-a-minute limit, which is for errors in a loop. A dashboard panel and table, and the prod check, read it. #245: the load test's browse scenario subscribes by OPML and leaves the Directory, which is ipx-directory's since #204, to it. CLAUDE.md records the owner's leave to EXPLAIN (ANALYZE, BUFFERS) any query on production, read only. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
