Package: zlib Version: 1.2.3-13 please define UNALIGNED_OK when building the amd64 target... unaligneds are very inexpensive on all intel and amd cpus.
i benchmarked gzip -9 on linux-2.6.17.tar with this define and i see a 2.5% speedup on p4, a64, and a 9% speedup on core2. the zlib source code has essentially the same longest_match() implementation as in the gzip source code, so i'm expecting similar improvements in zlib. note that this define wasn't necessary on 32-bit x86 because there's custom 32-bit assembly which uses unaligneds even more aggressively than the C code does even when given UNALIGNED_OK. thanks -dean p.s. i've submitted the same bug report against gzip to get the support enabled there as well. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
