I also made a comparison between gzip and bzip2 regarding
the compression ratio on a dump of my home directory (3.2GB)
bzip2 took about 74min to compress, gzip only 11minutes. And
in terms of compression ratio bzip2 was only 3% better than
gzip.
That's not a realistic test case. bzip2 normally takes trice the time
and compresses 10% better. I can't comment on compress.
