When optimizing Python ... JIT compilation doesn't have enough time to be amortized over the program's execution. Another consideration is that JIT compilers can increase the memory footprint of ...

PyPy aims to bridge this gap with its Just-In-Time (JIT) compiler. Unlike the traditional Python interpreter, which translates your ... up execution, it also requires additional memory to store ...

They aimed to make Python execution performance five times faster by leveraging the Low Level Virtual Machine (LLVM) compiler infrastructure to build a robust just-in-time (JIT) compilation engine.
