--- Comment #1 from Paolo Carlini <paolo.carlini at oracle dot com> 2011-12-02 10:12:26 UTC --- Francois, please take a look asap. Hans-Peter, can it be a memory issue? The recent changes imply that more memory is used by these data structures, and that is largely unavoidable, thus if there is nothing wrong algorithmically and the slow down is due to more memory being used, there isn't much we can do, besides tweaking the test for simulators, of course.
