   Oct 23, 2012 · A JIT compiler, in its most basic form, merely removes interpreter overhead, which accounts for some of the slow down you see, but not for the majority. A good JIT compiler also performs a host of optimizations which remove the overhead needed to implement numerous Python features in general (by detecting special cases which permit a more ...

   Jan 9, 2024 · In late December 2023 (Christmas Day to be precise), CPython core developer Brandt Bucher submitted a little pull-request to the Python 3.13 branch adding a JIT compiler. This change, once accepted would be one of the biggest changes to the CPython Interpreter since the Specializing Adaptive Interpreter added in Python 3.11 (which was also from Brandt along with Mark Shannon).

   Does CPython 313 have a JIT compiler?

   • CPython 3.13 comes with a JIT compiler (disabled by default for now). It doesn’t make things much faster yet, but the infrastructure is there. Just like the Specializing Adaptive Interpreter, it will slowly gain support for more Python and in theory make a future version faster. It works using a copy-and-patch approach.

   Does Python 313 support JIT?

   • That’s where Python 3.13 comes in. When you build Python 3.13 with the experimental JIT support, you’ll enable a lower-level execution layer called the Tier 2 interpreter, which breaks down Python bytecode into even more granular instructions.

   Which Python implementation has a JIT?

   • The only Python implementation that has a JIT is PyPy. Byt - PyPy is both a Python 2 implementation and a Python 3 implementation. There is now an experimental jit on the rust python interpreter github.com/RustPython/RustPython. The Numba project should work on Python 3.

   How to enable free threading & JIT compiler in Python?

   • Navigate into the parent folder containing the Python source code, which you extracted from the downloaded archive in the previous step: Make sure to adjust the path as necessary if you opted for a more recent Python 3.13 release. Now, you can run the configure script with custom build flags to enable free threading and the JIT compiler:

   How to build Python 313 without free threading & JIT support?

   • So, you’re going to build the vanilla flavor of Python 3.13 without free threading or JIT support. Ensure that your current working directory is where you compiled Python 3.13 before, and remove any generated build files with make clean. Then, configure the build without the experimental features and compile Python again.
