Libdeflate vs zlib. libdeflate (this library) also supports all three formats.
Libdeflate vs zlib. It is significantly faster than the zlib library, both for compression and decompression, and especially on x86 and ARM processors. gzip The DEFLATE format (rfc1951), the zlib format (rfc1950), and the gzip format (rfc1952) are commonly confused with each other as well as with the zlib software library, which actually supports all three formats. libdeflate itself is a library. libdeflate is a library for fast, whole-buffer DEFLATE-based compression and decompression. Level 9: libdeflate is about the same speed but compresses significantly better. It provides a fast and efficient implementation of these algorithms, focusing on both speed and compression ratio. In addition libdeflate is heavily optimized. Rust bindings to libdeflate, a high-performance library for working with gzip/zlib/deflate data. Jun 29, 2025 · The DEFLATE format (rfc1951), the zlib format (rfc1950), and the gzip format (rfc1952) are commonly confused with each other as well as with the zlib software library, which actually supports all three formats. So if all you look at is just speed then libdeflate will always win. k. The issue with those projects is that none are drop-in replacements for zlib, so they have very limited use. Mar 13, 2021 · Zlib-ng is about 4x faster than zlib (w/zlib-ng minigzip), and 2. Typical speedup over flate2 can be 1. But then, libdeflate and Oodle entered the chat! libdeflate libdeflate is an independent implementation of zlib/deflate compression, that is heavily optimized. Contains bindings for raw deflate, zlib, and gzip data. libdeflate is heavily optimized. In addition Libdeflate is a high-performance library for DEFLATE/zlib/gzip compression and decompression. Aug 26, 2023 · This is very useful if you need compatibility with gzip/zlib formats (e. Pros Significantly faster than zlib in most cases, especially for Aug 4, 2014 · CloudFlare’s zlib offers a good default file size for not much more time than libdeflate so is still a worthy contender. bam) (1 thread, elapsed ~= cpu time) May 10, 2023 · AFAIK libdeflate requires whole-buffer and does not support streaming. libdeflate is heavily optimized. I recently wrote bindings to libdeflate, which is a high-performance library for gzip, zlib, and DEFLATE (de)compression. (by zlib-ng) It is significantly faster than the zlib library, both for compression and decompression, and especially on x86 processors. zlib-ng was declared by its contributors as not production ready last time I checked. libdeflate Heavily optimized library for DEFLATE/zlib/gzip compression and decompression (by ebiggers) For compression, libdeflate currently has different advantages over zlib at different levels: Level 1: libdeflate is 1. 1x faster than stock gzip from my Scientific Linux 7. Zlib-ng loses a little on compressed size (due to 4-byte minimum match size instead of 3-byte). zlib-ng VS libdeflate Compare zlib-ng vs libdeflate and see what are their differences. Way faster, and a huge advantage is that the file format stays exactly the same; everything that could read or write EXR files in the past can still read/write them if libdeflate is used. 5-3x, depending on data. The Intel zlib specialises in fast compression at level -1, albeit at a weaker compression ratio. On the higher levels zlib-ng compresses twice as fast as zlib, with slight decrease in compression size which is expected. In addition, libdeflate provides optional high compression modes that provide a better compression ratio than the zlib's "level 9". Aug 9, 2021 · So, changing zlib to libdeflate should be a no-brainer. Level 12: libdeflate is slower than zlib Aug 4, 2014 · Like libdeflate this has a different and incompatible API to standard Zlib. The supported formats are: DEFLATE (raw) zlib (a. gzip (a. libdeflate doesn't do streaming. . It is significantly faster than the zlib library, both for compression and decompression, and especially on x86 processors. The library is designed to be easily integrated into existing projects and offers a simple API for developers. I'm not sure exactly how zlib-ng is Jan 31, 2023 · In the previous part I looked at generic lossless data compressors (zlib, lz4, zstd, brotli), and was thinking of writing about data filtering next. libdeflate VS zlib-ng Compare libdeflate vs zlib-ng and see what are their differences. Aug 9, 2022 · Compare libdeflate vs ZLib and see what are their differences. Benchmarks for this are estimated by applying a scaling (reduction) factor to the old benchmarks based on observed speedup for the other libraries. g. The purpose of this project is to give a reasonable good compression when you only have access to a pure Lua environment, without accessing to Lua C bindings or any external Lua libraries. zlib VS libdeflate Compare zlib vs libdeflate and see what are their differences. Reading (htslib’s test_view -B in. libdeflate (this library) also supports all three formats. DEFLATE with a zlib wrapper) gzip (a. DEFLATE with a gzip wrapper) libdeflate is heavily optimized. libdeflate は、データ圧縮および展開のためのライブラリで、特に 高性能 と 低リソース消費 を目指して設計されています。このライブラリは、 gzip 、 zlib 、raw DEFLATE 形式をサポートしており、以下の特長があります。 LibDeflate is pure Lua compressor and decompressor with high compression ratio, which compresses almost as good as zlib. For my use case, the compressed output was 8% smaller using libdeflate compression=12 than with gzip compression=9. zlib-ng zlib replacement with optimizations for "next generation" systems. Best of class! I recently ran across libdeflate by ebiggers, and it has some impressive benchmarks. zlib Cloudflare fork of zlib with massive performance improvements (by cloudflare) Bindings to libdeflate for DEFLATE (de)compression exposed as non-streaming buffer operations. Level 6: libdeflate is 2-3 times as fast and compresses about the same or very slightly better. 5-2 times as fast and compresses significantly better.
