+LZ4 - Extremely fast compression
+================================
+
+LZ4 is lossless compression algorithm, providing compression speed at 400 MB/s per core, scalable with multi-cores CPU. It also features an extremely fast decoder, with speed in multiple GB/s per core, typically reaching RAM speed limits on multi-core systems.
+A high compression derivative, called LZ4_HC, is also provided. It trades CPU time for compression ratio.
+
+This is an official mirror of LZ4 project, [hosted on Google Code](http://code.google.com/p/lz4/).
+The intention is to offer github's capabilities to lz4 users, such as cloning, branch, or source download.
+
+The "master" branch will reflect, the status of lz4 at its official homepage. Other branches will also exist, typically to fix some open issues or new requirements, and be available for testing before merge into master.
+
+
+Benchmarks
+-------------------------
+
+The benchmark uses the [Open-Source Benchmark program by m^2 (v0.14.2)](http://encode.ru/threads/1371-Filesystem-benchmark?p=33548&viewfull=1#post33548) compiled with GCC v4.6.1 on Linux Ubuntu 64-bits v11.10,
+The reference system uses a Core i5-3340M @2.7GHz.
+Benchmark evaluates the compression of reference [Silesia Corpus](http://sun.aei.polsl.pl/~sdeor/index.php?page=silesia) in single-thread mode.
