  • lrzip : ‘Lrzip uses an extended version of rzip which does a first pass long distance redundancy reduction. The lrzip modifications make it scale according to memory size. […] The unique feature of lrzip is that it tries to make the most of the available ram in your system at all times for maximum benefit. It does this by default, choosing the largest sized window possible without running out of memory.’
