Thanks. Francois, can you please further investigate this issue? In fact, if
the slowdown goes away with a preliminary reserve, it must be possible to
handle the problem rather easily, by tweaking the grow policy or something (We
should be a bit patient and consider that vs 4.4.x the implementation is almost
completely different)
