Do not assume that the way Linux manages threads is the only one. Mysql on FreeBSD does create threads; they are just not visible via top (in fact Linux is the only OS that shows threads in top). FreeBSD's threads system, however will not put those threads on multiple CPUs. You can work around this by building the mysql port with LinuxThreads: cd /usr/ports/databases/mysql323-server make WITH_LINUXTHREADS=yes This is only useful if your system is dedicated to mysql, though. If it is a combination webserver/database, the other CPU will be busy enough serving webpages, and FreeBSD's regular threads will do fine. -- Dan Nelson dnelson@allantgroup.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
