I've also got my version of parallel xz: https://github.com/vasi/pixz

It doesn't require use of large temporary files like pxz, and the xz files it produces can also be decompressed in parallel.

vasi, thanks very much for writing pixz, I've had a great experience working with it and it sped up my code very significantly.

The only thing I wish for is more documentation and inclusion in xz-utils (which I know is not up to you, but I'm hopeful).

Glad to hear it's been of use :)

The author of xz is working on a parallel compression implementation of his own, which will hopefully be in future versions of xz.

Looks worth trying out --

Can I suggest adding installation packages for: brew ubuntu (at least through launchpad)

[SnowLprd]

That looks very promising. As others have pointed out here, pixz would be much more accessible if one could simply install it via "brew install pixz" or "aptitude install pixz".

I welcome anybody who'd like to package it! I think it's already available in Arch Linux.
