dasini.net – Journal d'un expert MySQL

Dimitri KRAVTCHUK nous démontre, avec une batterie de tests, les évolutions en matière de performance apportées par MySQL 5.4:

• Huge performance improvement on InnoDB engine!
• MySQL 5.4.0 /Perf Version seems to be the most performant InnoDB implementation for the moment! (only except on the Read-Only workload @8cores where InnoDB plugin-1.0.3 is leading!)
• MySQL is outperforming PostgreSQL on my tests now!
• Regarding scalability, get a look at 8 vs 16 cores graphs, and you’ll see it’s the big step forward – no performance degradation on 16 cores is a very positive sign! and there is only 3 months distance between tests!
• LOCK_open needs a fix ASAP! 🙂
• Analyzing my test results, it’s too early to say InnoDB is scaling up to 16 cores, but the test results on 16 cores are already outperforming 8 cores, and I’m absolutely sure now – very quickly it’ll perform even better! so see you soon! :-))
