https://svn.boost.org/trac10/ticket/12461 <p> 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. </p> <p> 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. </p> <p> There is a minute increase in file size, much less than 1%. </p> <p> Please consider using pbzip2 to create the official .tar.bz2 files. </p> <p> (Not sure of component to file bug against!) </p> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/12461 Trac 1.4.3
