Disappointing OS X Lion Performance

I was really let down when I tested NoteCard on OS X Lion to find that the general performance of all low level drawing (using Apple’s 2D graphic framework CoreGraphics) is not as fast as on Snow Leopard 10.6. After searching around on Google I found that other users are having these problems (I.E. the same app on the same Mac running slower on Lion) so I can only assume this is a bug which is hopefully being fixed.

If you ever get a chance to run NoteCard on both 10.6 and 10.7 you’ll notice on 10.7 the dragging of cards is noticeably slower, which is the main problem. The animations seems comparable at first but I have at times caught the OS getting totally bogged down and struggling to perform basic animations at anything better than 10 FPS. My feel is the OS becomes slower after being in use for long periods of time.

Personally I haven’t even “upgraded” to Lion as my primary OS yet because it damaged support for some critical programs I use daily and in general I found the performance and system usage to be too high to warrant any minor features I may have been interested in.

Surely this is the first OS in my entire history with Apple which I wasn’t quick to adopt due to bugs and back tracking of features performance.
