How big are the 2 directories?

I carry a USB stick with about 15GB of data that I synchronize between 2
computers.  Usually, it takes about 2 minutes to sync them.   Sometimes I sync
it to a netbook and it's noticeably slower.  Clearly, hardware.  But, usually
there are not a lot of changes.  If there are large changes, like new
downloads, then it is much slower.  But, definitely, not on the order of 3
hours.
