In a rather biased article at mac os rumors http://www.macosrumors.com/20060710A1.php , theyve cited leopard to bring humongous performance improvements on itel equipped machines of up to 100%. According to them, leopard will redefine the term instantaneous for launching applications. Older PPC macs will see improvements of up to 25% in overall system speed. If this rumor has any grounding, this cat is already roaring! what do you think? Fanatical wishful thinking or possibly true?
