Here are the stats from my offline defrag. Factors other than size will come into play, as you can see below. The 94GB DB only took 76 minutes, whereas the 20GB took 99 minutes. That probably had something to do with the 94GB DB have about 89% whitespace in it. If you don't mind, put together some stats like I have below and post them to the list when you are done.
