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,
T G-R
