Your original post speaks of region growing, but the code is surface mesh simplification. Do you observe the same slowdown for both these use cases? How much slower is it?

Seems like a duplicate of https://github.com/CGAL/cgal/issues/3547, but it might give a reproducible way to fix it.

From what I see this has nothing to do with parallel nor with Lloyd. During the refinement process we break a facet for encroaching reasons, and when we update the...

My point was about encroachment seemingly being kind of equivalent to `FACET_VERTICES_ON_SURFACE`, and why was this wrong. I'll just look at the precise configuration since it gives a counterexample I...

No, the issue here is not related to optimizers.

The doc in `SDG_2` says: `If the GMP package is installed with CGAL, the template parameter EK has the default value: EK = Simple_cartesian, otherwise its default value is EK...

But this `result_type` will resolve to `NT`, see for example https://github.com/CGAL/cgal/blob/master/Number_types/include/CGAL/Lazy_exact_nt.h#L842. Are you getting some compilation error?
