Armin,
Yes it is the regular expression module. Great to know that it'll be faster in PyPy.
A large part of my application is creating and manipulating objects using Django's \
ORM and other modules. Would PyPy speed that up too? Or are those objects too \
short-lived (they only live within a request-response cycle) for JIT to be useful?

Is this "re" the regular expression module? If so, it's a standard
library module, so PyPy provides one too, rewritten in RPython. In
fact it is expected to be much faster than CPython's in the long run,
because regular expressions also use the JIT to compile regular
expression objects (which are originally some kind of bytecode).
A bientôt,
Armin.
