inetd.conf:

I was wondering:
I have an old computer running with an AMD K-6 proccessor.As such my resources are rather limited. I don't know if it was this way for everbody in the USA but this past holiday the internet slowed my computer down drastically.

So I think that to speed things up in general I should turn off unneeded services. So I find this guide that tells me that I should turn off RIP and SAMBA and others but now I can't find that page again to determine what the others are. Could anyone possibly suggest to me services I do not need on a machine that is just a home machine? Please tell me what the line I am commenting out does so I can comment it back in if I decide I need it (I am planning on getting another computer to play with networking or to super-computer it (can we do that with Mepis?).
In any case in my research I found that inetd.conf is what starts up the service but that appears to be incorrect because samba (smb, nmb) are not listed in that file. Nor are most of the other files that the document recommended I disable. I am including inetd.conf in the hopes that someone will look at it to make sure I haven't messed anything up before I save it to /etc.
Thanks for any help you are willing to give me.
