This is due to the Interactive's Fast File System (FFS).  The FFS reads in
the entire free list at mount time (and writes it out at unmount time).  So
your mounts/unmounts take more time when you don't have much data on a file
system (it's free list is longer).

BTW - This is discussed in the release notes pages 47 & 48 (the section on 
the FFS).
