Probably. If, when you run "ldd /usr/local/libexec/mysqld", you see a
line for libc_r, you're using userland threads (one CPU).

If you have the FreeBSD ports tree installed, you can cd into
/usr/ports/databases/mysql323-server, and run "make
WITH_LINUXTHREADS=YES install" to build mysql with Linuxthreads
instead of user-threads.
