Zstd offers a training mode to produce a dictionary used for compression, offering upwards of 3x more compression. Speed of compression and decompression is also improved. Zstd even without a dictionary outperforms xz, in particular decompression speeds. But at the sheer volume of xz (or bzip2?) compression for RPMs and LiveOS images in koji, I'd bet the compression time savings would be significant, without dictionary. And if training is possible, the advantage in compression ratio and performance would be huge. The Zstd patches for squashfs-tools don't appear to be upstream still for whatever reason, but patches are available. The kernel code for squashfs and Btrfs has been there for a while. So implementing this for LiveOS images is probably a good deal easier than whatever RPM and koji would have to learn to make it happen for all rpms. -- Chris Murphy _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx
