    pbzip2 1.05 optimized compile

    PBZIP2 is a parallel implementation of the bzip2 block-sorting file compressor that uses pthreads and achieves near-linear speedup on SMP machines. The output of this version is fully compatible with bzip2 v1.0.2 or newer.

    bzip2: (http://encode.su/forum/showthread.php?t=466)
    Code:
    bzip2.exe -zfk enwik8: 9.656 s
    bzip2.exe -dfk enwik8.bz2: 3.688 s
    Official pbzip2 compile:
    Code:
    pbzip2.exe -zfk enwik8: 6.413 s
    pbzip2.exe -dfk enwik8.bz2: 2.302 s
    Optimized pbzip2 compile:
    Code:
    pbzip2.exe -zfk enwik8: 5.417 s
    pbzip2.exe -dfk enwik8.bz2: 2.295 s
    Compression is 16% faster, decompression speed doesn't change.

    + no pthreadGC2.dll needed
    + autodetection of the number of cores

    This build should work correctly but have NOT been thoroughly tested. Then use it at your own risk.

    Please do NOT report any crashes, bugs, or any other problems to the author
