I know, but I have an iPad, so if you can post a simple mobile application that
shows the issue, I can test it.
-Slowness is coming from (regexp, etc) & garbage collection induced by the
allocations.
That's also what I have in mind, but the patch only aims at the garbage
collection + memory alloc.
That's why we need objective measures.
> ConstraintLayout / LayoutElementHelper are memory inefficient (and slow)
