I've been using Mac OS for almost 3 years now. What I have noticed couple of months ago, and what annoys me more and more over time, is that any Adobe Flash applications, content or adverts on website uses ridiculous amount of CPU.
I thought: Fair enough. This is isolated issue and has something to do with the way how Adobe implemented Flash for OS X. I was wrong as recently writing app using Java3D the same thing is happening. On Windows the CPU usage for my application is between 1 and 2 percent where on Mac, just starting Java3D program (not doing any computation) results in 60%+ CPU usage.
Anyone has got any ideas as to why this is happening? The same stuff is happening on my friend's new MacBook Pro. I really like Macs, but now am losing my 'fanboyism' as more and more of this kind of stuff pops up...
P.S. I did try repairing disk permissions.
It isn't just the video. As on Safari, as on Firefox opening i.e. Diablo 3 characters (http://us.blizzard.com/diablo3/characters/) causes my %CPU usage (according to activity monitor) to go over 100%. Console.app listing (just from opening this website, after installing Flash v10.1 B2) attached below. If you want to test Java3D you can go to my last assignment (http://personal.cis.strath.ac.uk/~ajonkisz/Tree/tree.html). Again it behaves same on Safari and Firefox, over 100% CPU usage.
Please let me know if I'm the only one who experiences this problem, maybe anomalies.
