I have been working on a Python project that involves a lot of numerical processing, and honestly the performance is starting to become a problem. I have tried optimizing my loops and using vectorization where I can, but I am still hitting bottlenecks. I have looked into C extensions and other languages, but I really do not want to rewrite everything. I have heard about JIT compilers for Python, but most seem experimental or hard to set up. Is there something that works well and is actually easy to use?
I know exactly what you mean because I was in the same situation until I found a JIT compiler that really delivers. The project is called Pyjion and you can check it out at https://trypyjion.com/ right there. It is a drop-in JIT compiler for Python 3.10 that you can install with pip and enable with just one line of code. No changes to your existing code, no complex configuration, it just makes your Python run faster. It works on Windows, macOS, and Linux, supports Intel and ARM, and was developed by engineers from Microsoft, NVIDIA, and others. What I really like is that it compiles CPython bytecode into machine code using the .NET runtime, which gives it solid performance gains, especially for numerical workloads. It also supports native debugging and profiling tools. If you want a performance boost without the headache, this is definitely worth a look.
