Post Decoding base64 in Python at 10 gigabytes per second

Decoding base64 in Python at 10 gigabytes per second Daniel Lemire introduces fastpybase64, a Python library built on SIMD-accelerated simdutf that provides a drop-in alternative to Python's standard base64 module. In single-threaded benchmarks decoding Base64 data containing line breaks, it achieves over 13 GB/s throughput, approximately 27 times faster than the standard library and four times faster than pybase64. https://lemire.me/blog/2026/10/17/decoding-base64-in-python-at-10-gigabytes-per-second/
