Both 5s broadcasters (the local traffic poll and the node traffic sync) shipped the complete client_traffics table on every cycle while a browser was connected. At 500k clients that is a 1.7s full-table read plus an 86MB marshal per job per poll — and the hub drops any payload over 10MB and sends an invalidate the frontend ignores for these message types, so past ~55k clients all of it was pure waste and the UI got nothing. Installs at or below 5000 clients (clientStatsSnapshotMaxClients) keep the exact full-snapshot behavior — it exists because a pure delta feed left UI rows stale when nothing moved in a cycle (see GetAllClientTraffics) — and the payload now carries snapshot=true. Above the threshold the jobs send only this cycle's active rows (the xray poll's active emails, or the emails online on the synced nodes) with snapshot=false, and scope the last-online map to those rows; the initial full map still arrives over REST and the clients page refetches every 5s. GetActiveClientTraffics gains the overlayGlobalTraffic pass so delta rows carry the same cross-panel usage as snapshot rows. The node job also stops reading the full last-online map before the has-clients gate, which was a wasted full-table read on every tick with no dashboard open. Frontend: useClients keeps its live summary strictly snapshot-driven (snapshot=false payloads skip the allClientStats replace and the summary falls back to the server-computed one); the per-row page merge and the inbounds-page merges already handle deltas.
