delete or hide unnecesary objects, images etc... they slow down DB ALOT! also try to drop your sync rate to about 20 if it still looks good... you could try reducing the amount of commands used, that is, use arrays and functions for repeated tasks, just generally try to keep the amount of information that is used to a minimum... and it helps to make use of external files, like reading text files for matrix data etc, less loading is needed for the main program that way...
hope i helped
