It also features an extremely fast decoder, with speed in multiple GB/s per core, typically reaching RAM speed limits on multi-core systems.\nA high compression derivative, called LZ4_HC, is also provided. It trades CPU time for compression ratio.\n\n|Branch      |Status   |\n|------------|---------|\n|master      | [![Build Status](https://travis-ci.org/Cyan4973/lz4.svg?branch=master)](https://travis-ci.org/Cyan4973/lz4) |\n|dev         | [![Build Status](https://travis-ci.org/Cyan4973/lz4.svg?branch=dev)](https://travis-ci.org/Cyan4973/lz4) |\n\nThis is an official mirror of LZ4 project, [hosted on Google Code](http://code.google.com/p/lz4/).\nThe intention is to offer github's capabilities to lz4 users, such as cloning, branch, pull requests or source download.\n\nThe \"master\" branch will reflect, the status of lz4 at its official homepage.\nThe \"dev\" branch is the one where all contributions will be merged. If you plan to propose a patch, please commit into the \"dev\" branch. Direct commit to \"master\" are not permitted.\nFeature branches will also exist, typically to introduce new requirements, and be temporarily available for testing before merge into \"dev\" branch.\n\n\nBenchmarks\n-------------------------\n\nThe benchmark uses the [Open-Source Benchmark program by m^2 (v0.14.2)](http://encode.ru/threads/1371-Filesystem-benchmark?p=33548\u0026viewfull=1#post33548) compiled with GCC v4.6.1 on Linux Ubuntu 64-bits v11.10,\nThe reference system uses a Core i5-3340M @2.7GHz.\nBenchmark evaluates the compression of reference [Silesia Corpus](http://sun.aei.polsl.pl/~sdeor/index.php?page=silesia) in single-thread mode.\n\n\u003ctable\u003e\n  \u003ctr\u003e\n    \u003cth\u003eCompressor\u003c/th\u003e\u003cth\u003eRatio\u003c/th\u003e\u003cth\u003eCompression\u003c/th\u003e\u003cth\u003eDecompression\u003c/th\u003e\n  \u003c/tr\u003e\n  \u003ctr\u003e\n    \u003cth\u003eLZ4 (r101)\u003c/th\u003e\u003cth\u003e2.084\u003c/th\u003e\u003cth\u003e422 MB/s\u003c/th\u003e\u003cth\u003e1820 MB/s\u003c/th\u003e\n  \u003c/tr\u003e\n  \u003ctr\u003e\n    \u003cth\u003eLZO 2.06\u003c/th\u003e\u003cth\u003e2.106\u003c/th\u003e\u003cth\u003e414 MB/s\u003c/th\u003e\u003cth\u003e600 MB/s\u003c/th\u003e\n  \u003c/tr\u003e\n  \u003ctr\u003e\n    \u003cth\u003eQuickLZ 1.5.1b6\u003c/th\u003e\u003cth\u003e2.237\u003c/th\u003e\u003cth\u003e373 MB/s\u003c/th\u003e\u003cth\u003e420 MB/s\u003c/th\u003e\n  \u003c/tr\u003e\n  \u003ctr\u003e\n    \u003cth\u003eSnappy 1.1.0\u003c/th\u003e\u003cth\u003e2.091\u003c/th\u003e\u003cth\u003e323 MB/s\u003c/th\u003e\u003cth\u003e1070 MB/s\u003c/th\u003e\n  \u003c/tr\u003e\n  \u003ctr\u003e\n    \u003cth\u003eLZF\u003c/th\u003e\u003cth\u003e2.077\u003c/th\u003e\u003cth\u003e270 MB/s\u003c/th\u003e\u003cth\u003e570 MB/s\u003c/th\u003e\n  \u003c/tr\u003e\n  \u003ctr\u003e\n    \u003cth\u003ezlib 1.2.8 -1\u003c/th\u003e\u003cth\u003e2.730\u003c/th\u003e\u003cth\u003e65 MB/s\u003c/th\u003e\u003cth\u003e280 MB/s\u003c/th\u003e\n  \u003c/tr\u003e\n  \u003ctr\u003e\n    \u003cth\u003eLZ4 HC (r101)\u003c/th\u003e\u003cth\u003e2.720\u003c/th\u003e\u003cth\u003e25 MB/s\u003c/th\u003e\u003cth\u003e2080 MB/s\u003c/th\u003e\n  \u003c/tr\u003e\n  \u003ctr\u003e\n    \u003cth\u003ezlib 1.2.8 -6\u003c/th\u003e\u003cth\u003e3.099\u003c/th\u003e\u003cth\u003e21 MB/s\u003c/th\u003e\u003cth\u003e300 MB/s\u003c/th\u003e\n  \u003c/tr\u003e\n\u003c/table\u003e\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flu-zero%2Flz4","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Flu-zero%2Flz4","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flu-zero%2Flz4/lists"}
