Hi. This is my first thread here. I've been using Mac for many years since Mac OS X came out, and always disappointed at the performance of flash on it. To be preciese, it is not a matter of performance but a CPU usage. For testing, I visited youtube.com for flash playing on PC(P4 1.5, notebook). There I played several contents and I confirmed it only used 2-4 % of the whole CPU power. The same contents, on Mac(my PowerBook G4, 1.5ghz) , It used about 40-50% of CPU power, and pretty soon the internal fan started.(yes, it got much hotter than before) I used very up-to-date version of Flash Player(PPC, r28), and All things are quite fast on my powerbook except Flash contents.(compared to PC) Is this the fault of Adobe(maker of Flash Player)? or of Apple(maker of Mac OS X)? I want to know the both of them have a will to fix this annoying Difference.
