Want to make your FastAPI application blazing fast? ⚡ In this video, we break down exactly how FastAPI handles different types of workloads and how you can optimize your backend for real-world performance. We cover the two most important types of tasks: Input/Output (I/O) based tasks (API calls, DB queries) CPU-intensive tasks (AI models, image processing) And more importantly: 👉 Why async alone is NOT enough 👉 When to use queues & workers 👉 How to scale FastAPI using uvicorn workers 👉 Real benchmarks comparing approaches If you're building production-grade FastAPI apps, this video will help you avoid common performance bottlenecks and design scalable systems. 🔥 What You’ll Learn Async vs Sync in FastAPI (real explanation) Why CPU-bound tasks block your app Queue + Worker architecture (best practice) How uvicorn --workers improves performance Ideal worker count strategy (I/O vs CPU tasks) Benchmark results (threading vs queue) 🧠 Key Takeaways Async = great for I/O tasks CPU tasks need background workers Workers = multiple FastAPI processes Correct architecture = massive performance gain 🛠 Tech Covered FastAPI, Python, AsyncIO, HTTPX, Redis, Workers, Queue Systems, Backend Scaling ⏱️ Chapters 00:00 – Introduction: Making FastAPI Fast 00:45 – I/O vs CPU Tasks Explained 02:10 – Async in FastAPI (When It Works) 03:30 – CPU Bottlenecks & Why Async Fails 05:00 – Queue + Worker Architecture 07:30 – Uvicorn Workers & Scaling 10:00 – Benchmarks & Best Worker Strategy 🚀 Join My Free Community! 👇 🌐 Nas.io - [Learn Everything About Chatbots](https://nas.io/learn-everything-about-chatbots) 📚 Master Google Dialogflow & Build Smart Chatbots!
