?? Django vs. FastAPI: The Concurrency Performance Battle

When building modern web applications, performance under load is critical. For developers, the choice of a framework can make or break an application's scalability. Two popular Python frameworks, Django and FastAPI, often come into this debate—each with its strengths.

Here's how they compare in terms of concurrency performance:

1?? Django

• Designed for synchronous workflows by default.
• Concurrency Limitation: Uses WSGI, which processes one request per thread.
• With async support introduced in recent versions, it can handle some concurrency, but the performance boost is limited.
• Best suited for applications that rely heavily on robust ORM, admin panels, or less-demanding I/O operations.

2?? FastAPI

• Built from the ground up with async in mind, leveraging ASGI.
• Concurrency Advantage: Handles thousands of concurrent requests with ease.
• Ideal for microservices, APIs with heavy I/O operations, and real-time systems.

Performance Takeaway: FastAPI shines in high-concurrency scenarios thanks to its async-first architecture, while Django remains the go-to for traditional full-stack apps where rapid development and ecosystem matter more than raw async performance.

?? The choice isn't just about speed; it's about aligning the framework with your project needs.
