lbzip2 – parallel bzip2 compression utility

lbzip2 is a multi-threaded implementation of bzip2, suited for serial and parallel processing.

On a multi-core computer, lbzip2 is commonly the fastest bzip2 decompressor for most bz2 files found on the internet. (On dual-core computers, the 7za utility from the p7zip-full package may prove more efficient).

lbzip2 integrates well with tar. Even on single-core computers, lbzip2 can speed up archiving in combination with tar, because lbzip2 allows compression to overlap with disk usage to a greater extent than bzip2 does.

Features include:

• Compresses and decompresses from pipes, using multiple worker threads.
• Contains a single worker decompressor as well.
• Input-bound splitter.
• Scales well to many cores.
• Significantly fater than bzip2 when compressing and decompressing.
