language implementation, including a fast Just-in-time (JIT) compiler.
The increased execution speed that PyPy provides has attracted many users,
-who now find their Python code runs
up to four times faster under PyPy

than under the reference implementation written in C.
However, in the presence of today's machines with multiple processors,
