Why Python Can’t Use All Your CPU Cores — The GIL Explained

Why Python Can’t Use All Your CPU Cores — The GIL Explained Ever wondered why your Python program doesn’t get faster even when you add more threads? The answer often lies in the Global Interpreter Lock, or GIL. In this video, we explain what the GIL is, why it exists, and how it affects multithreading and performance in Python. You'll also learn when to use multithreading, multiprocessing, and how engineers design high-performance Python applications. Understand the real reason behind Python’s performance limits and how to work around them in real-world systems. #python #gil #multithreading #multiprocessing #concurrency #performance #softwareengineering #coding
