If you don't need to send mail, you can turn off sendmail
. If you have no PCMCIA slots (that is, if you aren't using a laptop), you can turn off pcmcia
is a firewall, so if you don't need that (if you're already behind a firewall) you can disable it too.
isn't necessary if you don't plan on swapping hardware around very often. atd
could probably be turned off, since you already have crond
in there (read the manpages for this for details).
is a daemon to allow remote login (using secure shell) to your computer. If you don't plan on doing that, you can disable it too.
That's about all I know
edit: btw, it's pretty vague to talk about which OS is "faster".... it really depends on what you're doing. Are display updates slow? If so, make sure you have updated (and correct) video drivers installed, try using a different (less graphic-intensive) window manager like Fluxbox or Blackbox. If programs are slow to run, see if you can get ahold of versions for your architecture, or compile them for your architecture yourself (i.e., if you're using the i386 version, try getting one that's closer to your CPU, like i586 or athlon or whatever it is. Search for other threads on this topic, since it's been covered before.)
