installing Flash by default other than the stated reason of ensuring that
users always have the most up-to-date version. Having Flash installed can
cut battery runtime considerably—as much as 20 percent in our testing. With
a handful of websites loaded in Safari, Flash-based ads kept the CPU
running far more than seemed necessary, and the best time I recorded with
Flash installed was just 4 hours. After deleting Flash, however, the MacBook
Air ran for 6:02—with the exact same set of websites reloaded in Safari,
and with static ads replacing the CPU-sucking Flash versions.

not installing Quicktime by default other than the stated reason of ensuring

ads kept the CPU running far more than seemed necessary, and the best time I

Quicktime, however, the MacBook Air ran for 6:02—with the exact same set of

发帖数: 685 | 20 I don't know how HTML5 video is rendered on Mac. It is supposed to be
supported at browser level? However, I intend to believe quicktime is behind
Safari to render HTML5 video. Educate me if I have had been wrong :-)
I started talking QuickTime since some people tried to convince QuickTime
probably has worse performance when playing video compared with Flash. I 99%
am sure Flash is not a match to Quicktime about rendering video efficiently
on Mac.
I remember previously some people claim Flash's poor performance on Mac is
Apple's fault - Apple did not release hardware acceleration API to Adobe for
implementing Flash on Mac. This is lying since other rendering software not
utilizing the acceleration API doesn't exhibit the problems Flash on Mac
presents.
