Apparently xz is a very good data compressor

See:

-rw-r--r-- 1 root root 496700 May 31 00:06 centos-5-x86_64.tar
-rw-r--r-- 1 root root 166133 May 31 00:53 centos-5-x86_64.tar.bz2
-rw-r--r-- 1 root root 185911 Mar  9  2010 centos-5-x86_64.tar.gz
-rw-r--r-- 1 root root 105060 May 30 23:56 centos-5-x86_64.tar.xz

So we have the following compression ratios
gzip: 0.37 (2.7 times smaller)
bzip2: 0.33 (3 times smaller)
xz: 0.21 (4.7 times smaller)

Wow!
