Found a handy link to an online pdf describing the available configuration sections, along with values, for J.D. Edwards. Its evidently a chapter from the McGraw Hill book, "J.D. Edwards One World: The Complete Reference".
The performance of J.D. Edwards can be tuned dramatically by configuring the JDE.INI file appropriately. Of course, I'd consult with your friendly neighborhood CNC before changing any of these values yourself!
