Unless you upgraded to the new version, you are probably still on the old SysV startup scripts version.

Here's what to do.

install sysv-rc-conf
Run sysv-rc-conf and toggle off anything you dont' want running. If you aren't sure what it is, leave it alone.
Next you'll need to do this:
cd /etc/rc0.d
then rename any ones in there that you disabled in sysv-rc-conf.

Do the same in /etc/rc6.d

reboot faster
