I had noticed that our rpm files and especially .drpm files can get a lot smaller by compressing them with xz or gzip.

The current stance is that *zstd* is the new kid on the block (and rpm supports it now, too), compressing nearly as strong as xz, but in the timespace of gzip.
[Fedora] the on-disk usage goes up by ~5-15% (zstd 9 vs xz 2)
The graph at https://raw.githubusercontent.com/facebook/zstd/master/doc/images/DCspeed5.p... is based on a linguistic corpus. Would be cool to see it for the set of BRPMs of a distribution. Then again, there is no good trivial command (like "gzip -d a.gz; gzip -9 a") yet to do such a test. :-/
, depending on the package. So for the moment, I've shelved the idea of zstd RPMs until I can get a better picture on how to get better compression without it taking longer than xz. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
