Explore the significant performance enhancements coming to CPython 3.14 and planned for 3.15 in this 26-minute conference talk from EuroPython 2025. Learn about the major speed improvements that mark a return to the substantial performance gains seen in Python 3.11, after the relatively modest improvements in versions 3.12 and 3.13. Discover the key technical innovations driving these performance boosts, including a faster interpreter implementation, the introduction of a JIT (Just-In-Time) compiler, optimized garbage collection mechanisms, reduced overhead in reference counting operations, and the implementation of tagged integers. Gain insights into the development roadmap and understand how these improvements will make CPython 3.14 significantly faster than its predecessor, with even greater performance gains anticipated for version 3.15.
