Server: - lib/cache.ts: tiny TTL memo for hot paths. - lib/rcon.ts: pooled connection with 30s idle close and one-shot retry; was opening a fresh TCP per RCON call. - /api/status: race protocol-ping + RCON with Promise.any (was sequential with 5s timeouts) and memo 3s; adds Cache-Control. - /api/players: memo 10s, invalidated on mutations. - /api/mods: getModDetails memo 10s (invalidated on install/remove) — eliminates per-request readdirSync/statSync/AdmZip parse. - /api/analytics: reverse-scan JSONL to window cutoff (O(window) vs O(file)) and memo 30s. - /api/logs: memo 2s to throttle journalctl spawns during Live mode. Client: - StatusCard + ServerControls: staleTime 5s, both poll every 10s, dedup via shared query key. - Analytics: staleTime 30s; memoize sparkline SVG paths. - Modrinth search icons + mc-heads avatars: width/height + loading=lazy + decoding=async. - next.config.ts: images.remotePatterns for future next/image migration, explicit compress=true.
