I ran a quick test where I copied my Python 2.5 installation on
Windows and cleared out the site-packages folder and ran the test from
the stackoverflow thread.
With crufty site-packages: 0.18s
With empty site-packages: 0.16s
With -S (either installation): 0.10s
So there does appear to be some improvement, but only a fraction of
what I get by using -S.
