    lzbench - an in-memory benchmark of open-source LZ77/LZSS/LZMA compressors

    Attached is an in-memory benchmark (with source code) of the fastest open-source LZ77/LZSS compressors. I've joined all compressors into a single exe. At the beginning an input file is read to memory. Then all compressors are used to compress and decompress the file and decompressed file is verified. The "i" option selects number of iterations (default 1) and displays average time of N iterations.

    This approach has a big advantage of using the same compiler with the same optimizations for all compressors. The disadvantage is that it requires source code of each compressor (therefore Slug or LZ4 are not included).
