[opensuse-packaging] Call for testers: SSE/MMX/SSSE3 powered zlib
Hi: Brave testers, will be cool if you can install an experimental/development version of zlib, that uses SSE/MMX/SSSE3 to improve the performance of the library from 2 to 6 times, depending what features your CPU support. (determined at runtime) If you want to contribute, add the following repository to zypper http://download.opensuse.org/repositories/home:/elvigia:/zlib/openSUSE_11.4 and dup from it. (if 404, it hasnt published yet) It works just fine in two x86_64 machines I have used, but Im interested in getting feedback from 32 bit users,specially those running less than current CPUs. Finally please note that zlib is used by almost everything,either directly or indirectly and if something goes wrong your system will likely become unusable. Im looking forward to your feedback. -- To unsubscribe, e-mail: opensuse-packaging+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-packaging+help@opensuse.org

Would it be possible to load the library with LD_PRELOAD and test with gzip? -- Per Jessen, Zürich (8.6°C) -- To unsubscribe, e-mail: opensuse-packaging+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-packaging+help@opensuse.org

gzip does not link to libz currently.. ldd /usr/bin/gzip linux-vdso.so.1 => (0x00007fffa57d5000) librt.so.1 => /lib64/librt.so.1 (0x00007f085ee23000) libc.so.6 => /lib64/libc.so.6 (0x00007f085eab6000) libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f085e899000) /lib64/ld-linux-x86-64.so.2 (0x00007f085f02c000) -- To unsubscribe, e-mail: opensuse-packaging+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-packaging+help@opensuse.org
