Runtime type checking overhead without compile-time guarantees
4/10 LowLibraries 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.

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.
