   PyPy often runs faster than the standard implementation CPython because PyPy uses a just-in-time compiler. [3] . Most Python code runs well on PyPy except for code that depends on CPython extensions, which either does not work or incurs some overhead when run in PyPy.

   Plot 1: The above plot represents PyPy3.10 (pypy3.10-jit-64) benchmark times normalized to cpython. Smaller is better. It depends greatly on the type of task being performed. The geometric average of all benchmarks is or times faster than cpython. How has PyPy performance evolved over time?

   Oct 10, 2024 · PyPy is much faster than CPython; we’ll see tests later on where PyPy performs about 7 times faster. In some cases it might even be tens or hundreds of times faster than CPython. So how does PyPy achieve its speed?

   How fast is PyPy compared to CPython?

   • On the (geometric) average, PyPy speeds up Python by about 4.7 times over Python 3.7, with some tasks accelerated 50 times or more. While JIT optimizations of certain kinds are being added to new versions of the CPython interpreter, they aren’t of the same scope and power as what PyPy does right now.

   Is PyPy 3 faster than Python 2?

   • Some more comparisons and numbers would have been great. PyPy has had Python 3 support for a while, but according to this HackerNoon post by Anthony Shaw from April 2nd, 2018, PyPy3 is still several times slower than PyPy (Python 2).

   What is the difference between CPython and PyPy?

   • Whereas CPython compiles Python to intermediate bytecode that is then interpreted by a virtual machine, PyPy uses just-in-time (JIT) compilation to translate Python code into machine-native assembly language. Depending on the task being performed, the performance gains can be dramatic.

   • Long-term evidence is showing that PyPy runs certain Python codes slower than CPython and this drawback seems to be rooted very deeply in PyPy. Secondly, the current version of PyPy consumes much more memory than CPython in a rather large set of cases. So PyPy didn't solve the memory consumption problem yet.

   Does PyPy run on CPython?

   • PyPy is written in Restricted Python. It does not run on top of the CPython interpreter, as far as I know. Restricted Python is a subset of the Python language. AFAIK, the PyPy interpreter is compiled to machine code, so when installed it does not utilize a python interpreter at runtime.

   Mar 16, 2024 · Definition: PyPy is an alternative implementation of Python, featuring a Just-In-Time (JIT) compiler designed to execute Python code faster than CPython. Performance: PyPy can significantly outperform CPython on long-running programs due to its JIT compiler, which optimizes frequently executed code.
