Because of the dynamic nature of Java, with 7 or so active threads running at the same time, even in a "single-threaded" app, I would recommend that you time at at least 100k operations before you make any kinds of assumtions ;) - Gunnar _______________________________________________ Qt-jambi-interest mailing list [email protected] http://lists.trolltech.com/mailman/listinfo/qt-jambi-interest
