Description:
Performance of Python
programs has been a major focus of development for the language over the last five years or so; the Faster
CPython project has been a big part of that effort.
One of its subprojects is to add an experimental just-in-time (JIT) compiler to
the language; at last year's PyCon US, project member Brandt Bucher gave an introduction to the copy-and-patch JIT
compiler. At PyCon US
2025 , he followed that up with a talk on "What they don't tell you
about building a JIT compiler for CPython" to describe some of the things
he wishes he had known when he set out to work on that project. There
was something of an elephant in the room, however, in that Microsoft
dropped support for the project and laid off most of its
Faster CPython
team a few days before the talk.
