I tried this interchange of FLLarge* with standard dictionaries, like suggested above by Mariano. The results are astonishing: ************************** 240 seconds with FLLarge* classes 111 seconds with standard Pharo classes ************************** Thats a time reduction by more than 50%! Does this mean that FLLarge* classes are obsolete and can be substituted by standard classes? (At least in the newer Pharos versions) Cheers, Andreas -- Andreas Brodbeck www.mindclue.ch
