How can I speed up my MOPAC job? It seems slow.
There is a piece of software made by Motorola called LibMoto that was written to optimize certain math functions. This software has been found to make a noticable speed improvement in MOPAC jobs. There may be some compatibility issues when using LibMoto, so we do not recommend the software. If you would like to use it, you must do so at your own risk. Check out Motorola's LibMoto FAQ or download Libmoto for your OS.
