Summary

This forum post on zhichai.net outlines a performance enhancement strategy across four areas: caching, database optimization, concurrency, and monitoring. The caching layer combines file-based caching stored under data/cache/ with a memoization mechanism (sg_memoize). Database optimizations include enabling SQLite WAL mode and FTS5 full-text search indexing to improve write throughput and query speed. Concurrency is addressed through parallel sub-agent execution and concurrent news fetching. Finally, the monitoring stack covers log rotation and metrics-based monitoring. The post serves as a concise checklist sourced from Stratagem.php, summarizing how layered caching, WAL mode, FTS5 indexes, and parallel processing work together to reduce latency and improve system observability.
