Description : parallel bzip2 filter
Lbzip2 is a Pthreads-based parallel bzip2/bunzip2 filter, passable to GNU
tar with the --use-compress-program option. It isn't restricted to regular
files on input, nor output. Lbzip2 utilizes multiple threads and an
input-bound splitter even when decompressing bz2 files created by standard
bzip2. Successful splitting for decompression isn't guaranteed, just very
likely (failure is detected). Splitting in both modes and compression
itself occur with an approximate 900k block size.
On an Athlon-64 X2 6000+, lbzip2 was 92% faster than standard bzip2 when
compressing, and 45% faster when decompressing (based on wall clock time).
On a 2x Quad-Core Opteron 2352, lbzip2 was 588% faster than standard bzip2
when compressing, and 394% faster when decompressing (based on wall clock
time).
