Create Solid Archive (best compression) with 7z

7z a -mx=9 -ms=on archive.7z files_for_archiving/
Creates a solid archive with the highest possible compression (Ultra). Advantage of 7z is that it will use all the processor cores to create the archive. (Ok. at least version 9.04 does)
Sample Output
