Bzip2 can also do much better than gzip, but as you'd expect it depends on 
the type of data (as the algorithms have different approaches).  Bzip2 is 
computationally heavier so it definately slower :)

Also worth noting that bzip2 defaults to -9 while gzip defaults to -6 (but 
Greg did have both explicitely set to -9 in his tests).
