I just found out about rzip and 7zip, new-ish file compression utilities. Being obsessive about performance and statistics and stuff, I ran a few tests: all these required the compressor to produce its "best" (most compressed) output.
|compressor||size of compressed file (%)||CPU time (s)|
So gzip is far, far away the fastest (which explains its continued widespread use) but using one of the others could save significant amounts of space with very large files - if you have the time to spare.
