From the developer:
If you use spinning disks, you’ll have noticed that over time it takes longer and longer to access your files, to start your applications and even to start your machine.
This is an unavoidable consequence of the way hard disks work. It can be made better or worse by the design of the filesystem (and, actually, in this respect your Mac’s filesystem, HFS+, is one of the best), but in the long run there’s really no way to avoid this effect.
You may want to check out more Mac applications, such as MacCleanse, CleanApp or Deeper, which might be similar to iDefrag.
