I'm 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. For more details, keep reading. Is this guy more or less wrong in his explanations about threads ? (I was said so) As I know nothing about threads, but I noticed a similar behavior on MacOSX, and MySQL performances are as bad on FreeBSD as on MacOSX, compared to linux. any explanation/confirmation/correction greatly appreciated. patpro
