Yes, it is skewed.  It does give us a reference point of how fast 
certain operations perform (creations, deletetions, etc).  Two other 
good tests would be a balanced set of medium size, typical writes (1k, 
100k, 1MB, 10MB) as well as some tests of larger writes (100 MB, 500 
MB, 1 GB, 5 GB).  If there is enough interest there, I'm sure we could 
do something similar.
