zlib-rs 0.4.2 Released: A Blazing Fast Compression Library
2025-03-16
zlib-rs 0.4.2 is out, boasting significant performance improvements! It's now (to our knowledge) the fastest API-compatible zlib implementation for decompression, and outperforms the competition in key compression scenarios. This release leverages clever multiversioning and DFA optimizations to efficiently select the optimal implementation at runtime, leading to dramatic speed gains. Benchmarks show zlib-rs significantly outpacing zlib-ng and zlib-chromium in decompression. While further compression performance improvements are planned, zlib-rs is already exceptionally fast and is seeking funding to complete the remaining work.
