Mastering Node.js Performance
summary
Shows concrete wins and costs: replacing synchronous file/hash calls with asynchronous ones (benchmarked with autocannon) raises throughput from ~123 to ~428 requests and drops medians from 4.8s to 2.2s and 97ths from 7.8s to 2.4s. Running independent DB queries in parallel cuts latency (example saving eight entities). Avoid the node cluster model in production in favor of nginx/iptables. Resolve a million promises: Bluebird 1.4s vs native 1.8s. Use typed arrays, classes, avoid delete, and move low‑priority jobs to separate processes.
