In part it's inherent problems. Python is way dynamic and therefore hard
to speed up.
But, Pythoneers also know it can be done, by looking at other languages
that are dynamic, such as Smalltalk and Lisp, which have managed to gain some
quite massive improvements in speed.
Pythoneers are actively looking at ways to speed up Python code, so in part
it's also simply maturing. I heard Python *has* speeded up a lot since
earlier versions, in fact.
