Hi all,

the Parallel XZ just reached usable state so if you want to take
advantage of parallel LZMA compression, please give it a try before
its inclusion into Fedora.

PXZ homepage is:

Sources and YUM repos are available at:

Please note that it saves most of the compression time for large
files. E.g. file is split to parts of the size of the dictionary for
given compression level (8MiB for default -6 compression) and then
runs compression itself in as many threads as your system allows.

Benchmarks and usage cases are presented on the PXZ homepage.
