Why should you have to tune anything ? Did you tune the Oracle Server
install ? If not, you should not have to tune the FreeBSD install,
that wouldn't be fair. If you tune FreeBSD, you should tune the Oracle
Server install too. It is pretty easy to win at least 30% in
performance for certain workload by choosing the right kernel
configuration.
