Where did you take these figures from? I could only find a 4% slow down for Leopard versus Tiger on a 867 MHz G4 with 1 GB of memory. http://lowendmac.com/ed/royal/09sr/leopard-vs-tiger.html > ... G4 laptops in the 1.5-1.67 GHz range, not older slower PPC Macs. I've installed -side-by-side- 10.2 Jaguar, 10.3 Panther, 10.4 Tiger and 10.5 Leopard (with the Open Firmware hack) on my QS 2001 with Dual 800 MHz G4 7450 processors. I have to say that the QS has now 1.5 GB memory. And I cannot see Leopard being so horrible as you say. It works like a charm. > The possible reasons to upgrade to Leopard include: Time Machine, > Spaces, and some newer software that isn't Tiger compatible. Are there > other reasons? For me the main reason was Time Machine, which is absolutely great! A reason to stay with Tiger is the Classic support, which you loose if you upgrade to Leopard (sigh). I don't use Spaces. I don't like it at all, it's not really well integrated. I also don't use Dashboard. > I don't think this is enough reason to upgrade myself, so I've left my G4 Mini with Tiger. I upgraded my G5 PowerMac to Leopard, and I'm too lazy to downgrade, so it's stuck, but luckily the G5 has enough horsepower for the slowdown to be not too bothersome until just recently. For the G5 it might be worth the upgrade, since Leopard is able to run 64-bit GUI applications. If memory is an issue for you (for an application you're using) then this could greatly speed up your workflow. The G5 is a 64-bit processor. Leopard is a 64-bit capable operating system with a 32-bit kernel. All you need is >4 GB or memory and a 64-bit application using this memory. If you're below the magical 4 GB this feature doesn't affect you and you can happily stay with Tiger. > When I migrate onto an Intel machine I'll likely downgrade the G5 also. In > my opinion, Tiger is the "best" OS for PPC Macs, and is with certainty the > "fastest". Sorry, I cannot see that. Leopard maybe a little slower, but it integreates more features that slow it down. Do that with Tiger and it will be slower too. If you're so much into the speed thing, why don't you still run 10.2 Jaguar? This would really give your system a boost. > Intel Macs likely need Snow Leopard now, but I have no experience with Snow > Leopard, so I'm not certain. Snow Leopard is really the way to go on an Intel Mac. It has been optimized for the Intel architecture and has a lot of speed-ups under the hood. Although it really looks like Leopard and the look-and-feel hasn't really changed at all. A user might not even notice a difference. All in all I would assume it is more stable then Leopard was (on Intel-Macs).
