• Vectorization in Python — NumPy vs Pandas vs Polars vs Numba

  Posted on:April 14, 2025 |  at 10:00 AM

  Systematic benchmarks comparing four vectorization approaches across different dataset sizes and operation types. When to use NumPy directly, when Polars wins, and when Numba's JIT compilation is the only answer.

• Pandas Performance — Stop Using .iterrows() (with Benchmarks)

  Posted on:March 14, 2024 |  at 10:00 AM

  Benchmarking five approaches to row-level operations in pandas — from the naive .iterrows() to fully vectorized NumPy operations — with real timing numbers. Shows 100-1000x speedups using vectorization and explains why Python's object model makes .iterrows() so slow.
