On a related note. I've noticed that it sometimes takes a very long time to copy an application (package containing maybe several thousands of seperate files) from say a mounted .dmg to my preferred location on my HD. I have had this take more than 5 minutes with something like a 20 MB app (!).
They only thing I can think of is that spotlight is indexing all of the contents. So maybe in your case the spotlight indexing is also one of the culprits.
