uvloop
High-performance asyncio event loop alternative built on libuv.
Core Idea
uvloop swaps Python’s default event loop with a libuv-powered version. Because it manages I/O in optimized C code, it can reduce latency and CPU usage for IO-bound FastAPI services without changing your application code.
Why It Matters Here
Mathbong’s performance lessons show how to run uvicorn --loop uvloop --http httptools to squeeze more requests per second from the same hardware. Pairing uvloop with good caching and connection pooling sets a realistic baseline before scaling infrastructure.
