Unlikely. The way Mac OS X handles its files, manually defragmenting with a utility will not have any benefit, and actually may decrease performance in some situations. See this Apple support document for explanation:

Mac OS X already includes an "automatic" but limited defragging system. It is not user-controllable. For 90%+ of users, this is all that's required.
If you routinely work with very large files (HD video, huge Photoshop files, that sort of thing), you may wish to occasionally defrag your boot drive or your scratch drive to optimise performance. You can do this with commercial programs like iDefrag, but I prefer the simpler, old-fashioned approach:
1. Make a clone of your boot drive using SuperDuper or CarbonCopyCloner or whatever else you like. Test that the clone is fully bootable and good.
2. Boot from the clone drive.
3. Erase the boot drive.
4. Restore from the clone drive.
You're done. The boot drive is now defragmented.
