chore(serverinfo): POLL_INTERVAL 4s -> 1s - #4
Merged
Conversation
Companion to ReduxStation/website#10 which moves the landing-page poll to 1Hz. Without matching server-side cadence the browser sees the same JSON for 4 fetches in a row and the timer steps 4s at a time. Cost: /world/Topic ?status runs sub-millisecond per call on DD's main thread; 1Hz is ~0.1% of one core. The 700-byte atomic file write hits page cache, not disk per write. The public-log-parser still polls its own 60s cadence.

`docker-compose.yml` `serverinfo-updater.POLL_INTERVAL` 4 -> 1.
Companion to `ReduxStation/website#10` which moves the landing-page
poll to 1Hz. Without matching server-side cadence the browser sees
the same JSON for ~4 fetches in a row and the timer steps 4s at a
time again.
DD-side cost: `/world/Topic ?status` is a sync proc, sub-millisecond
per call. At 1Hz cadence that's ~0.1% of one main-thread core.
