Isn't the basic strength of lzma a very big dictionary window?

No it cannot. Recompressing something that is already compressed,
normally ends in growing the final result.

Generally speaking, trying to compress something that's already
compressed doesn't gain you anything.

Starting with Fedora 12, RPM packages are compressed using XZ instead of
gzip. As a result, the F12 ISOs are smaller:
F11 DVD sizes (bytes):
i386: 3683829760
ppc: 4606894080
x86_64: 4268124160
F12 DVD sizes (bytes):
i386: 3204427776
ppc: 3738935296
x86_64: 3537600512

Dear fellow users,

deltaiso. Although I have never downloaded one, I ask if one can save more
bandwidth if we use lzma compression. I ask this q
