Weblbzip2 is a free, multi-threaded compression utility with support for 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 ...

The decompression normally has lower CPU-intensity than the compression (where multiple cores are often involved). You wouldn't have much of an advantage anyway as the read/write-operations are more of the bottlenecks during decompression. Share. chef pee pee song
