lbzip2 2.5 Parallel bzip2 compression utility

lbzip2 is a multi-threaded compression utility with support for the bzip2 compressed file format. lbzip2 can process standard bz2 files in parallel. It uses POSIX threading model (pthreads), which allows it to take full advantage of symmetric multiprocessing (SMP) systems. It has been proven to scale linearly, even to over one hundred processor cores. lbzip2 is fully compatible with bzip2 – both at file format and command line level.
