Mastering Node.js Performance
summary
Shows concrete wins and losses: replacing synchronous file/hashing with async raises throughput from 123 to 428 requests and cuts the 50th/97th percentiles from 4.8s/7.8s to 2.2s/2.4s (measured with autocannon); resolving a million promises runs ~1.8s native vs ~1.4s with Bluebird; typed arrays cut bulk insertion from ~723ms to ~25ms; cluster master process adds overhead so nginx/iptables beat Node cluster for throughput; fix sequential I/O with Promise.all, avoid delete, prefer classes and typed arrays.
