Description
pbzip2 is a parallel implementation of the bzip2 file compressor; files compressed using it are compatible with regular bzip2, but to get speedup while decompressing with pbzip2 the file must have been compressed with pbzip2.
In a quick test, decompressing/untaring Boost 1.61.0 is more than 4 times faster on an 8-CPU system using pbzip2 than using regular bzip2 on the same machine.
There is a minute increase in file size, much less than 1%.
Please consider using pbzip2 to create the official .tar.bz2 files.
(Not sure of component to file bug against!)
