I don't understand how pypy can improve performance. Am I correct that pypy
is an effort to implement Python as much as possible in Python? And am I
correct that implementing a module in C will probably speed it up? Combining
these two, wouldn't implementing Python in Python slow things down? If so,
what is the advantage of pypy?

I don't want to clutter pypy-dev with these questions, because they must
be very trivial and Pypy-people probably have better things to do than
answering trivial questions ;)

When I started with Python, I did not know the difference between a language
an IDE, a compiler and an interpreter; you can search Google and look at my
first posts here to check I'm right :)

Gerrit.
