Compression performance plots are often done with something like the Silesia corpus. Linux distributions have rather different proportions of file types […] a lot of machine code, and even more data files, and probably not so much text and images. Since our data set is also 2.8 orders of magnitude bigger, rerunning a compression shootout will give more detail. http://paste.opensuse.org/15790105 http://inai.de/files/openSUSE-compression.ods
http://paste.opensuse.org/view/26689667 (upload complete but viewer broken?) http://inai.de/files/openSUSE-compression-201904.ods The takeaway for 2019-04 (over 2018-10) is: * Distribution grew by 11% (uncomp.) * gzip lost a bit (no more than 2%) in speed * zstd lost ~7% in speed; has a large outlier -25% on z16/z17 * bzip2 lost ~15% in speed * xz wins up to 2% in speed * (therefore I would assume Spectre mitigations are not a factor) -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
