Just FYI: The 7-zip algorythm is called LZMA as far as I know. A quick
Google search brought up these links to benchmarks:
http://www.linuxjournal.com/node/8051/
http://tukaani.org/lzma/benchmarks

Not sure how valid those are but if I interpret them correctly, LZMA is
quite slow and very memory hungry but does achieve very good compression
ratios.
