H3 Library Performance Benchmark
— A systematic performance benchmark was conducted on two prominent Python libraries implementing Uber's H3 geospatial indexing system: h3-py (official, C-based) and h3o-python (Rust-based). Results show h3o-python consistently outperforms h3-py on core operations, achieving over 2x speedup for coordinate conversions and up to 13x faster neighbor queries, while area calculations remain comparable.
