🔒 What is the GIL (Global Interpreter Lock) and How Does It Impact Python?

If you’ve ever heard that Python "doesn’t do real parallelism" or that "multithreading in Python is limited," you’re likely bumping into one of the most discussed aspects of the language: the GIL — Global Interpreter Lock. In this article, we’ll dive...

Understanding Multi-Threading and Multi-Processing in Python

Introduction Applications often need to do many things at once: download files, process images, serve web requests, or compute huge datasets. This is where concurrency and parallelism come in. While Python supports both, it has some surprising quirks...

Demystifying Python Concurrency: Benchmarking threads with GIL enabled-disabled, Processes, and Async

Alright, folks. Let's talk about Python concurrency. And by "talk," I mean "I'm going to rant about it while showing you some actual data. We're diving deep into the GIL, threads (with and without that pesky GIL), processes, and async, and we're goin...

Python GIL 병목 현상 시각적으로 분석하기

들어가기에 앞서 블로그를 구독해주고 계신 분들 감사드립니다 :) 들어가며 오늘은 Python 의 GIL(Global Interpreter Lock) 에 대해서 알아보고 왜 GIL 로 인해 CPU-Bound 작업에서 영향을 받을 수 있는지를 알아보고, 이걸 직접 코드로 작성하여 시각적으로 분석해보는 시간까지 가져보도록 하겠습니다. 아마도 장문의 글이 예상되니 꼼꼼히 읽으면서 따라오시길 바랍니다 Python 이 실행되는 방식 우리가 보통 별다른 구...

[Python] Global Interpreter Lock (GIL)

GIL GIL ensure that only one thread executes Python bytecode at a time, which means it prevents multiple threads from executing Python code concurrently. GIL works like this: There are three threads, but they are not running concurrently. One need...

Concurrency in Python

When high-performance is required There are several ways to achieve concurrency in Python and each of them has its own trade-off: A-sync, Multi-Thread and Multi-Process. First of all, let’s break the myth — Python is NOT a single threaded language! Y...

Python Multitasking: Key Practices and Challenges

When I first encountered the Python language, I was amazed by what you could do with so little code, and it has been one of my favourite programming languages since. Some time ago, I faced a problem where I was trying to create something like a web s...

Disabling GIL - Unleashing the True Power of Python

Introduction Python is finally getting rid of its major limitation, the Global Interpreter Lock (GIL), which it has had since 1991. Before explaining what the GIL is, let's understand how computers and programming languages were designed in the 1990s...

Data Race in Python despite GIL?

Data race While the definite definition of data race differs with the concurrency model and the language, it's safe to assume that data race is when 2 or more threads try to access the same memory where at least one of them is a write operation. Seei...
