Runtime type checking overhead without compile-time guarantees

4/10 Low

Libraries that provide runtime type checking in Python add approximately 50% performance overhead while only catching errors at runtime. This creates a false trade-off where developers get stricter type checking but lose performance without gaining the compile-time safety of statically-typed languages.

Query: “What are the most common pain points with Python in 2025?3/27/2026

I have used that library on multiple projects for my job. It makes the code run about 50% slower, on average, because all the type checking is done at run-time.
