Hi there! I have just found out that bzip2 is _really_ _great_ for large files. I have tar'ed a whole debian-installation (1.2 gigs). This tar, compressed with gzip, has a size of ~390MB. The same tar, compressed with bzip2 has a size of 110MB!!!
So for every body out there: If you have a large file to compress (and enogh time resp. CPU-power) then check out bzip2. It is much slower than gzip, but (at leas for sufficient large files) much better. So long Andreas Maresch
