Revisiting FreeBSD vs. Linux for MySQL

Posted by timothy on from the base-for-your-data dept.

Dan writes "Jeremy Zawodny, who looks after all of Yahoo!'s MySQL servers says MySQL now runs very well on FreeBSD. He is no longer steering people toward Linux. There are two important things you should do to make the FreeBSD/MySQL combo work well: (1) build MySQL with LinuxThreads rather than FreeBSD's native threads, and (2) use MySQL 4.x or newer."

  1. linux threads on freebsd -release or -stable by JDizzy · · Score: 4, Interesting

    Given that FreeBSD -current 1:1 threads are not 100% yet, the native FreeBSD threads will not grant the optimal performance compared to the linux threads. Yahoo probably uses a RELEASE version, or a -STABLE version of FreeBSD on their production systems, so the KSE probably isn't an option anyways. Once KSE is finished, I'm sure we will reviste the "FreeBSD V. Linux" threads war again. No granted I'm a bit biased toward FreeBSD, but I think that since the same folks control the LIBC taht are also creating the KSE (kernel scheduled Entities, aka kernel aware threads) that FreeBSD will have a bit tighter integration when all things are said and done.

    It isn't a lie if you belive it.
  2. Anticipatory scheduler by placiBo · · Score: 2, Interesting

    I'd like to see similar comments running the anticipatory scheduler for Linux and a quad processor SMP box vs FreeBSD. Thats where the differences in SMP performance and the threading implementation will show.
