FIrst off I do have a better Mac. But the old Mini still seems to work OK, well after addressing a hard drive problem. So I have a spare copy of Leopard. Just installed it onto a fresh drive and did all the software updates and let the spotlight index finish. It works OK but wow is it SLOW. How slow? I type "www.cnn.com" in to the address bar in Safari and the letters don't appear as I type. The after a few seconds the beach ball appears for about 12 seconds then finally the URL I typed appears. Many times windows and icons do not track the mouse. It is hard to edit text if the hi-light area lags a good "three count" from the mouse pointer. Basically the G4 is not usable. Specs are basic: G4, 1.25Ghz, 1GB RAM, 5400RPM ~40GB drive. DVD burner "super drive". Question: Should I go back to Tiger? I have the discs for Tiger also being unused and available. Second question: Could the horrible performance be caused by a hardware problem? Again this is a brand new Leopard install and everything seem to function correctly if you give it enough time. Activity Meter shows half the RAM is free (green) and o page outs, zero swap in use. Maybe I should simple install a copy of BSD UNIX or even Linux. I think All I need to run on that Mini is a web browser and "text edit" The main computer is a 24" iMac but the kids some times need a second computer for homework.
