[Python-Dev] insertdict slower?

Are you using an AMD chip?  They have different cache behavior than the
Pentium I expect Jeremy is using.  Different flavors of Pentium also have
different cache behavior.  If the slowdown his box reports in insertdict is
real (which I don't know), cache effects are the most likely cause (given
that the code has not changed at all).

Jeremy saw "about 15%".  So maybe that's just *loud* noise <wink>.
