Fold the home-page prewarm into the page warmer - #139
Merged
Merged
Conversation
pages/home.py started its own prewarm thread at import, which raced the page warmer for the GIL while both built the same per-market frames. On the VPS after the 2026-09-25 16:17 restart the home prewarm and the queued weekly-report requests all finished together ~3.5 minutes after boot. Now home.warm_caches runs inside main.warm_page_caches, second, after the newest weekly report and before the boards. That also means it only runs in the process that serves requests (the import ran it in both under --debug's reloader), and it is re-warmed after a new week, where before a release left the home cards cold until the first visitor. Local boot, process start to served: newest weekly page 3.2s -> 2.0s, home prewarm 2.7s -> 1.0s, everything warm ~10s either way (two runs each).

pages/home.pystarted its own prewarm thread at import. That thread raced the page warmer for the GIL while both built the same per-market frames. After the 2026-09-25 16:17 restart on the VPS, the home prewarm and the queued weekly-report requests all finished together, about 3.5 minutes after boot (see #137).Change
