-------------------------------------
Hi Maurice,
The "real world" application i'm working on can not be shared :-(
the ConstraintLayout / LayoutElementHelper are slow on mobile (ios). On a
recent desktop environment, you will not notice the pb (except the memory
allocations).
Slowness is coming from :
- the code (regexp, etc)
- the garbage collection induced by the allocations
I will try to provide a benchmark that can be run on desktop.
