I have played a bit with bzip2 and have managed to get compression 10.4% faster: Compression / Decompression of test file in seconds old: 42.94 / 11.54 new: 38.90 / 11.48 Decompression time improved very slightly. What I changed is some compiler options (nothing fancy, just using -Os and -O3 in the right places) and I made bzip2 static. Building it static seems to help caching, since quite a bit of the extra performance comes through this. Sure, that might use some more memory, but it's just a few kilobytes. All tests were run on my Pentium-M. I'd like to know if other people also get higher performance with this one, especially on AMD processors. If at least perfomance does not _de_crease for anyone else, I hope this can go into SLICK. You can get the rpm at [1] (install with --force) and the source at [2]. Note that I have only added a patch for the makefiles and changed the spec-file.
