MySQL Performance: 5.4 outperforms PostgreSQL 8.3.7 @dbSTRESS !

Forget to say, I've also tested PostgreSQL 8.3.7 during the last benchmark serie with dbSTRESS!

A big surprise - if two years ago on the same workload PostgreSQL was two times faster (see: http://dimitrik.free.fr/db_STRESS_BMK_Part2_ZFS.html ), now it's MySQL 5.4 outperforming PostgreSQL!

  • Read-Only workload: MySQL is near two times faster now! (13.500 TPS vs ~7.000 TPS for PostgreSQL)

  • Read+Write workload: MySQL performs as well or better (7.000-8.000 TPS vs 6.000-7.000 TPS for PostgreSQL)
