Package: zlib1g Version: 1:1.2.7.dfsg-13 Severity: wishlist File: zlib Hi,
It seems Intel has recently released a set of patches to zlib: https://github.com/jtkukunas/zlib This adds a few optimizations and new modes; in effect, it seems the new “medium” mode gets you get about 70-80% faster compression for 1-2% larger files (you can tweak this, of course). It remains compatible with regular zlib, both ways. Some of this would only be appropriate for modern x86 (e.g., the use of the crc32 instruction for hashing), but some of it is general speedups that would be useful to zlib as a whole. I know reconciling this so that we get speedups for x86 and no regressions for other platforms isn't a small task, but wishlist bugs don't need to be small, do they? :-) -- System Information: Debian Release: 7.6 APT prefers stable APT policy: (750, 'stable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 3.16.3 (SMP w/40 CPU cores) Locale: LANG=en_DK.UTF-8, LC_CTYPE=en_DK.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages zlib1g:amd64 depends on: ii libc6 2.13-38+deb7u4 ii multiarch-support 2.13-38+deb7u4 zlib1g:amd64 recommends no packages. zlib1g:amd64 suggests no packages. -- no debconf information -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
