I'm happy to report that my testing found that
compression level 0 is about ten times as fast as
the rest.
Compression level 0 was even five times faster
than gzip.
rzip's second stage uses bzip2, which uses
compression levels from 1 to 9.
While rzip also allows compression levels from 1
to 9, it has the quick compression level 0 too.
What does compression level 0 do?
Does compression level 0 skip the bzip2 stage?
If so, wouldn't compression level 0 permit it to
be used as a filter, which is vital for speeding
up network transfers by allowing simultaneous
compression, sending and decompression?
Thanks,
Kingsley
