Description Jan Psota 2018-01-10 17:51:44 UTC

...and enabled by default.

Especially since portage BINPKG_COMPRESS can be set to lzip,
what makes a great sense on multi-core == popular machines.
(switching from xz to lzip [=plzip] quicken "quickpkg rust"
from 2m to 40s on 4-core AMD)

The pigz/pbzip2/lbzip2 symlink hack relies on the fact that bzip2/gzip is installed to /bin, so we can make an extra symlink in /usr/bin. This can't really happen when the reference archiver is in /usr/bin. You can create a symlink in /usr/local/bin locally for it, I suppose.

That said, you don't want to use parallel xz or lzip. It splits the compressed file into ${jobs} parts reducing the compression ratio.

Having _only_ app-arch/plzip works like magick for me :-)
(I wrote how many times faster it is)

What about !app-arch/lzip if +symlink is set?

I wonder if we could revisit this now we have app-alternatives/.

Comment 4 Jan Psota 2022-12-14 17:29:17 UTC

Right! :-) Just like with:
app-alternatives/gzip USE="pigz (split-usr) -reference"
app-alternatives/bzip2 USE="lbzip2 (split-usr) -pbzip2 -reference"
(works for me)
