AbsoluteLayout has the potential to perform layouts without a single measure call. This makes it very powerful for performance. If AbsoluteLayout cannot be used, consider RelativeLayout. If using RelativeLayout, passing Constraints directly will be considerably faster than using the expression API. That is because the expression API uses JIT, and on iOS the tree has to be interpreted, which is slower. The expression API is suitable for page layouts where it only required on initial layout and rotation, but in ListView, where it‘s run constantly during scrolling, it hurts performance.
