Performance on iOS
Some notes on performance:
When animating objects, use instead CSS-Transformations. CSS-Transformations are hardware accelerated on iOS devices, so they are much faster!
- Animated GIF’s
Animated GIF’s are displayed as you expect in mobile safari. The smaller the image, the better the performance. Keep in mind that the frame rate will be slower compared to a desktop browser. The animations halts, when the user is scrolling and is continued, when scrolling stops. Scrolling smoothness will also be influenced by the animated GIF.
For additional perfomance information take a look at Thomas Fuchs’s notes on “making an iPad App and making it really fast”.Keep in mind that performance differs on various hardware generations.
