When should I use the Python Performance Optimization skill?

Use this skill whenever your Python application runs slowly, consumes excessive memory, or fails to meet the scaling requirements of a production environment.

What is the primary rule of optimization followed by this skill?

The core principle is to never optimize without profiling first, ensuring that 80% of the effort is spent on the 20% of the code causing the actual bottleneck.

Can this skill help reduce infrastructure costs?

By improving execution efficiency and reducing resource consumption (CPU/RAM), this skill directly assists in lowering cloud compute and scaling costs.

Does this skill help with numerical and scientific computing?

Yes, it provides specific guidance on vectorization with NumPy and JIT compilation with Numba to accelerate numerical loops and calculations.
