mac OSX server 10.5 + Powerbook G4

I know that I don't need the server software in order to be able to use iChat!

I will be managing a network of computers that are going to be using those services via the Mac OS X Server computer.

Ah.

Well, turning on all services except for Mail would be extremely taxing on a server. That's a lot of services to be running on a computer that's so underpowered. I'm going to go out on a limb and say you're experiencing a slowdown because you're running WAAAAAY too many services on that computer.

Try turning all services off except for iChat, File Sharing and Web Sharing. See if you notice any speedup after that.

I will 'only' be using iCal, iChat, File Sharing, Web but now I understand this will probabely ask to much from my old G4. Or because it's a laptop?

Anyway, I'll reinstall with only iCal activated and we'll see what happens then.

And in the meantime I'll wait for the new MiniMac...

You don't have to reinstall the operating system -- simply open "Server Manager" and turn off the other services.

All of the services will be installed on your machine -- you do not have control over what's installed and what's not. You only have control over what services are actually turned on and active.

As I wrote, after upgrading the server software to the most recent version the PowerBook doesn't start up at all so I will have to reinstall.

And, as I wrote, I will only activate iCal, just to see what happens.
