    I just noticed that playing YouTube Video in Safari or Google Chrome the CPU usage is not less than 70-75 % on both cores ( MacBook 2.4ghz unibody with SL 10A432 32bit kernel ). On Firefox the CPU usage on the same YouTube video is no more than 40-45% on both cores.

    Anyone else notice this ?

    I guess it may happen because flash plugin is 32 bit and used in some sort of sandbox in Safari now because Safari is 64bit and flash plugin is 32 bit ( in Chrome everything run in sanbox and I got the same CPU usage on Leopard ). Firefox is 32 bit application as Flash is and I'm guessing thats why it uses less CPU.

    Flash performance in safari at 64bit is really bad, in 32bit mode it's better but still bad.

    I don't know if it's Apple's fault, or Adobe's fault... but this performance is really a shame.

    I'm getting similar percentages. Firefox seems to be more efficient at the moment.
