of course ... in my case i had  to sacrifice the space in order to finish
the job in less than 24 hours :) 

The better compression on bzip2 part isn't linear (in my tests) with the amount
of time it takes to achieve it. I bet there are some knobs to modify amount of
buckets or other memory related settings in bzip2 to make work faster... 

if not, maybe another algorithm...but [bg]zip are so widespread they may become
the one choice if you have to distribute the files to a wider audience.
