pxz results in significant time saving when generating xz filetypes for
images due to parallelization support
This adds another host tool dependency - on my Ubuntu (14.04) system, even
if 'xz' is installed, 'pxz' is not and I'd have to add it. Since *.xz seems
to be the new fashion/trend, perhaps this choice might be optional/configurable?
I provided pxz recipe as well.. so I don’t get it where is host tool dep.
Fair enough, I missed your additional recipe.
a simple test on ubuntu build host with 16 CPUs
