The Fastest Python Struct?

The article explores the performance tradeoffs of Python's various struct-like types, focusing on startup and type-definition costs rather than runtime business logic. Extensive benchmarks reveal that NamedTuple sits in the middle of the pack, while msgspec and C-backed implementations deliver the fastest type creation and startup times.
