Reduce startup time for non-networked machines System
If your mac is not on a network one thing that will speed up the boot time in OSX is to manually set the IP address. The system will spend less time "Initializing network" and result in a faster boot time. This doesn't effect any dial-up service because that is on a different port.

[Editor's note: I haven't tried this myself. I assume that the IP address should be placed in the Ethernet area of the Networking preferences panel, but have not verified that. Clarifying comments from those without networks are welcomed!]

fixed ip adress starts faster
Authored by: Giel on Mar 23, '02 04:15:35PM

I noticed this effect as well. Using fixed ip adresses is faster than getting those ip-adresses from a dchp server. I guess it also depends on the speed of the dchp server. That's why all my computers use fixed ip adresses in my (home-)network. I noticed this on linux and windows as well.
If you don't need an adress, then trying to get one from a non-existing dchp server will probably take even longer!

fixed IP address Manual ethernet area

Yes this definitely works. Saves a lot of time at boot up. I picked a number from the private range for my machine (192.168.x.x). I use

turning off ethernet also works
Authored by: bdidonna on Mar 24, '02 09:19:14AM

If you are not using the ethernet port at all, you can set the system to ignore it. Under the network control panel Show menu, select "Active Network Ports", then turn off ethernet. The system never tries to configure ethernet at startup, so you don't have to wait for it to time out on a non-existent DHCP server.

turning off ethernet also works

Yep turning off ethernet also works, However folks might need their ethernet port for their printer and if that is the case you need to have that port active. My setup is a Cube with an old LaserWriter NTR, it is a great printer that I did not want to get rid of it so I bought an ethernet to appletalk adapter and it worked. However that is when I noticed OSX taking longer to boot. Presumably because the ethernet port was active but there was nothing connected to it. As a result it went looking for an IP address and it would time out before continuing to boot up. By manually giving the machine an IP number it no longer does this. This trick is useful to a small number of users but, if you are in this situation it does help.
