* LZ4Sharp Port of Yann Collet's LZ4 algorithm to C# by Clayton Stangeland. Original LZ4 algorithm can be found at (http://code.google.com/p/lz4) it was created by Yann Collet. See license.txt for project license. * Build Building in Debug or Release will use the already generated C# files LZ4Compressor.c and LZ4Decompressor.c are updated by manually comparing to the original LZ4 code and fixing any C# differences from C but leaving some of the macros to make comparing easier. Then building in the Generated configuration will only build the LZ4SharpGenerator project which has a prebuild event that uses the MinGW gcc from CodeBlocks to generate the C# files from LZ4Compressor.c and LZ4Decompressor.c. * Timings Compression times do not include disk I/O. P4 = Pentium 4 2GHz 32 bit Windows XP i5 = Intel i5 2.67 GHZ *** bit Windows 7 running LZ4Sharp in *** bit LZ4Sharp = Timings for 'webster' from silesia corpus (http://sun.aei.plsl.pl/~sdeor/index.php?page=silesia) memcpy and LZ4 = Timing for file 'webster' in silesia corpus in m2mark.exe from http://sd-1.archive-host.com/membres/up/182754578/m2mark.zip (or from link to benchmark program at http://code.google.com/p/lz4) gzip = GZip from the Intel compiler built as a dll and accessed from C# by PInvoke Ratio = compressed size / decompressed size (lower is better) | Computer | Type | Compression (MB/s) | Decompression (MB/s) | Ratio (%) | |----------+----------+--------------------+----------------------+-----------| | P4 | memcpy | 217 | | | | P4 | LZ4 | 82 | 304 | | | P4 | LZ4Sharp | 43 | 150 | | | P4 | LZ4Sharp | 49 | 181 | | | i5 | memcpy | 1658 | | | | i5 | LZ4 | 270 | 1184 | | | i5 | LZ4Sharp | 207 | 758 | 49 | | i5 | LZ4Sharp | 267 | 838 | 47 | | i5 | gzip | 48 | 266 | 33 | ** Conclusion: LZ4 C# is about 2/3 the speed of the c version. (Also, LZ4C# is slightly faster on the whole silesia corpus than on just the 'webster' file) LZ4 C# Compressed silesia corpus is 47% of uncompressed LZ4 C# Compressed 'webster' file is 49% of uncompressed
