Parsing JSON at tens of gigabytes per second in Python, via SIMD
smilelamp · hn · 2026-10-12
Daniel Lemire benchmarks an approach that pushes JSON parsing in Python to tens of gigabytes per second by leveraging SIMD-accelerated string processing (simd-style) ahead of the parsing path. The post compares throughput against the standard library and options like or, and discusses when the optimization is worth adopting.
