This is a patched version of zlib, modified to usePentium-Pro-optimized assembly code in the deflation algorithm. Thefiles changed/added by this patch are:README.686match.SThe speedup that this patch provides varies, depending on whether thecompiler used to build the original version of zlib falls afoul of thePPro's speed traps. My own tests show a speedup of around 10-20% atthe default compression level, and 20-30% using -9, against a versioncompiled using gcc 2.7.2.3. Your mileage may vary.Note that this code has been tailored for the PPro/PII in particular,and will not perform particuarly well on a Pentium.If you are using an assembler other than GNU as, you will have totranslate match.S to use your assembler's syntax.
