Interesting!  What kind of improvement do you see, roughly?

When I added zlib compression I was surprised to learn that here 
it made no significant difference in wall clock time (less than a 
minute; 5% or so) or CPU time.  The disks they spin and CPU she is 
fast, but still I would have noticed a spike.

Kind regards,
