How to boost -webkit-transform performance: helpful tips

Utilizing webkit-transform: translate3d and various other properties extensively on a mobile app designed for iPhone has greatly improved performance due to hardware acceleration. The majority of features are functioning at an optimal level, ensuring smooth operation. It is crucial to avoid overburdening the system with too many tasks simultaneously.

I have successfully implemented a realistic swiping simulation that closely resembles native functionality. However, upon adding the final 2% of features, I encountered some issues with image redrawing during the animation process while swiping. Once all four images have loaded and the swipe is completed, performance improves significantly. Yet, when switching between hidden and visible states, the problem resurfaces.

My theory is that there may be an internal buffer limit being reached, necessitating a reload each time the issue arises.

In light of this situation, my query extends beyond my specific case. I am interested in learning about the diverse performance optimizations that developers have employed for -webkit-transform. Rather than focusing solely on my dilemma, I seek insights into the broad spectrum of solutions others have discovered to meet their individual requirements.

If this inquiry garners responses, it could serve as a valuable reference for those encountering similar challenges in the future.

Answer №1

While it may be common knowledge, ensuring that the element being transformed utilizes 3d transforms where feasible can greatly enhance performance on devices that support hardware-accelerated transforms (such as iOS).

An easy way to achieve this is by including:

transform: translate3d(0,0,0);

with the required prefixes in the element's CSS, and then proceed to animate it normally using either 2d or 3d transforms.

Answer №2

Although it may sound unusual, I encountered a similar problem and found a solution by implementing -webkit-perspective: 1000.

I'm not sure why this specific property helped with the transitions, but it worked for me in resolving the issue.
