• Caching: In-memory cache with 30-second TTL
  • Pre-warmed on server startup
  • Async background refresh when expired
  • Stale-while-revalidate pattern for optimal UX
• Refresh: Client-side polling (60s interval)

Performance

Without cache:

• API response time: ~15 seconds (blocking)
• Problem: Each request blocks Node.js event loop

With cache:

• Cache hit: <100ms (~365x faster)
• Cache miss: ~15s (first request only)
• Stale cache: <100ms while refreshing in background
• Cache TTL: 30 seconds

The caching system ensures:

• Lightning-fast responses for most requests
• No blocking of concurrent requests
• Graceful degradation when cache expires

這個監控工具整體質量不錯，介面美觀大方，手機和電腦都能用，資料會自動重新整理不用手動操作。但作為 v0.1.0 版本，還存在一些小問題：部分說明文件語言不一致，版本號顯示可能有誤導，核心功能的實現比較紮實可靠。適合需要隨時檢視 OpenClaw 執行狀態的使用者使用。
