Eshte shtuar nj\u00eb realizim eksperimental i JIT-kompajlluesit, i cili lejon nj\u00eb rritje t\u00eb konsiderueshme t\u00eb performanc\u00ebs. P\u00ebr t\u00eb aktivizuar JIT n\u00eb CPython, \u00ebsht\u00eb shtuar mund\u00ebsia nd\u00ebrtimore «—enable-experimental-jit», p\u00ebrdorimi i s\u00eb cil\u00ebs k\u00ebrkon instalimin e LLVM si nj\u00eb var\u00ebsi shtes\u00eb. Procesi i p\u00ebrkthimit t\u00eb kodit t\u00eb makin\u00ebs n\u00eb JIT \u00ebsht\u00eb nd\u00ebrtuar duke p\u00ebrdorur arkitektur\u00ebn «Copy-and-Patch», n\u00eb t\u00eb cil\u00ebn me ndihm\u00ebn e LLVM krijohet nj\u00eb skedar objekt n\u00eb formatin ELF, q\u00eb p\u00ebrmban t\u00eb dh\u00ebna mbi instrukset e bytecode dhe informacion mbi z\u00ebvend\u00ebsimin e nevojsh\u00ebm t\u00eb t\u00eb dh\u00ebnave.
