Assuming this is a call for numbers ...
$ zcat xview3.2p1-X11R6-LinuxELF.2.src.tar.gz | bzip >xview3.2p1-X11R6-LinuxELF.2.src.tar.bz
BZIP, a block-sorting file compressor. Version 0.21, 25-August-96.
$ ls -l xview3.2p1-X11R6-LinuxELF.2.src.tar.gz xview3.2p1-X11R6-LinuxELF.2.src.tar.bz
-rw-r--r-- 1 sr1 users 2115537 Oct 22 10:20 xview3.2p1-X11R6-LinuxELF.2.src.tar.bz
-rw-r--r-- 1 sr1 users 2843166 May 30 17:10 xview3.2p1-X11R6-LinuxELF.2.src.tar.gz
So bzip is much better on text-like files.
It took twice as much time as gzip -6, and 8MB RAM.
