Doubling the speed of jpegtran with SIMD

This post details the optimization of the jpegtran image compression tool by leveraging SIMD instructions. It demonstrates how profiling and targeted code improvements, specifically in Huffman coding functions, led to a significant speedup (2.25x) in image processing. This directly contributes to the efficiency of Cloudflare's Polish product, enhancing website content optimization by making image compression faster and more resource-efficient.
