A long time ago I saw a thread (maybe on this very list) with concrete
numbers.  I only remember the conclusion:

  - everything in one zip file (including the Python stdlib) was fastest
  - everything unzipped was 2nd fastest
  - multiple zipped eggs were slowest

This was probably done in the times of rotational hard disks.  It would
be interesting to see someone repeat that experiment.
