ckolivas / lrzip
A compression utility that excels at compressing large files (usually > 10-50 MB). Larger files and/or more free RAM means that the utility will be able to more effectively compress your files (ie: faster / smaller size), especially if the filesize(s) exceed 100 MB. You can either choose to optimise for speed (fast compression / decompression) or size, but not both.
tars the directory, then maxes out all of the system's processor cores along with sliding window RAM to give the best BZIP2 compression while being as fast as possible, enables max verbosity output, attaches the extension .bzip2-lrz, and finally gets rid of the temporary tarfile. Uses a tempvar lrzdir which is unset automatically.
Checks integrity, then decompresses the directory using all of the processor cores for max speed, enables max verbosity output, unarchives the resulting tarfile, and finally gets rid of the temporary tarfile. Uses the same kind of tempvar.
Go to https://github.com/ckolivas/lrzip/releases and downlaod the tar.gz file from the top. cd to the directory you downloaded, and use tar xvzf lrzip-X.X.tar.gz to extract the files (don't forget to replace X.X with the correct version). Finally, cd into the directory you just extracted.
