IMHO on Leopard (compared to Tiger) the slowdown is mostly due to lack of Quartz Extreme and Core Image on the graphics performance side (meaning: _not_ processor performance). The slowdown is most noticeable already in Tiger with things like Spotlight indexing in the background (which gladly can be disabled) and Dashboard and TimeMachine and maybe other services that lay hard work on a slow processor and/or use up valuable system memory. If you disable all that, you should be happy. Additionally, you can get rid of some eye-candy that will load your graphics card (and processor, if you graphics card is without QE/CI) unnecessarily. http://www.thexlab.com/faqs/performance.html (Very good on systems with /old/ graphics cards, such as a ATi Rage 128 or so.) For Leopard, I think you really *have to* have a good graphics card that features both, QE and CI. Otherwise it will always feel like you have the brakes on… Just my 2¢ Andreas aka Mac User #330250 -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
