Defrag.NSF is already one of the fastest defragging utilities available, but there are steps you can take to improve its processing performance:

1. Turn off Performance logging. You will find this option on the Technical Settings Tab

2. Make sure that no (or as few as possible) Domino maintenance utilities are running while Defrag.NSF is doing its thing. Defrag.NSF will track changes and this can slow things down.

3. Make sure you are only defragging the files you need to. For example, our research has shown that defragging fulltext indexes is basically a waste of time because they quickly become fragmeneted again.
