MySQL vs PostgreSQL Performance Benchmark: Latency, Throughput, and Saturation
The benchmark comparing MySQL 9.0 and PostgreSQL 17.0 shows PostgreSQL consistently achieving lower insertion latency, roughly double the throughput (≈19 k QPS vs 10 k QPS), using less CPU, memory and disk I/O, while both hit an 80‑connection pool limit and PostgreSQL maintains stable read latency as MySQL’s performance degrades beyond ~5.5 k QPS.
