That's expected: PyPy uses more memory than CPython in general, with
the exception of programs using a lot of instances --- instances are
more compact in PyPy than in CPython.  Moreover, there is a large
"base size" of some MBs in PyPy.  You need programs consuming a lot
more than 7.8MB to see a possible memory benefit in PyPy, just like
you need programs running for much more than 0.1 seconds to see speed
benefits.


A bientôt,

Armin.
