   Sep 23, 2013 · A: PyPy isn't 100% compatible with CPython because it isn't simulating CPython under the hood. Some programs may still depend on CPython's unique features that are absent in PyPy such as C bindings, C implementations of Python object&methods, or the incremental nature of CPython's garbage collector.

   3 days ago · Note also that our JIT has a very high warm-up cost, meaning that any program is slow at the beginning. If you want to compare the timings with CPython, even relatively simple programs need to run at least one second, preferably at least a few seconds. Large, complicated programs need even more time to warm-up the JIT.

   The effect that you get in CPython has clearly been described as a side-effect of the implementation and not a language design decision: programs relying on this are basically bogus. It would be a too strong restriction to try to enforce CPython’s behavior in a language spec, given that it has no chance to be adopted by Jython or IronPython (or any other port of Python to Java or .NET).

   Here's some news: gcc is available on Windows too! (CPython on Python takes advantage of gcc's label pointers to do faster bytecode dispatching using 'computed goto'. This is not supported by MSVC, so CPython on Windows is a little slower than it need be, because of a misconception.) I actually have an interpreter project of my own, for Windows.

   Sep 21, 2018 · C API Overview¶ In CPython, which is written in C, Python objects are represented as PyObject*, i.e. (mostly) opaque pointers to some common "base struct". CPython uses a very simple memory management scheme: when you create an object, you allocate a block of memory of the appropriate size on the heap.

   Why do some programs still depend on CPython?

   • Some programs may still depend on CPython's unique features that are absent in PyPy such as C bindings, C implementations of Python object&methods, or the incremental nature of CPython's garbage collector. This answer does not cite any benchmarks or provide references.

   Why is CPython the most conservative runtime?

   • Because CPython is Python’s reference implementation, it has historically been the most conservative runtime in terms of optimizations. Python’s maintainers want CPython to be the most broadly compatible and standardized implementation of Python available.

   Why is PyPy slower than CPython?

   • 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.

   Should I use CPython or PyPy?

   • Swap out CPython for PyPy, and for the most part you’re done. Also, all major platforms are supported in 64-bit editions—Windows, CentOS 7-compatible Linux (both ARM64 and Intel), and macOS  (also both ARM64 and Intel). PyPy has always performed best with “pure” Python applications.

   Is CPython faster than Python?

   • A common complaint about Python generally, and CPython in particular, is speed. By default Python runs many times slower than C, sometimes hundreds of times slower. PyPy JIT-compiles Python code to machine language, providing a 4.8 times speedup over CPython on average. Some tasks run as much as 50 times faster.
