I've implemented this new strategy in the more_unboxing branch of the SVN. You can find some description (and micro-benchmarks) there: http://caml.inria.fr/mantis/view.php?id=5204 If numerical code is the bottleneck of one of your applications, it would be helpful if you could you try out the more_unboxing branch (forked from the trunk in january 2011, IIRC) and report the results on Mantis. Thanks! Alain
