Hi, lz4 is growing in popularity as a compression algorithm. As of systemd 216, systemd-journald supports lz4 (in addition to xz). Benchmarks[1] were provided at the time Zbigniew wrote the patches to show the impressive drop in CPU required to compress journal files.
There's already a feature request to enable this[2], and a complaint about the excessive CPU usage of XZ in the presence of a program which doesn't behave[3] in some given environment. So, with that, is anyone opposed to moving lz4 to [core] so that systemd can sanely depend on it?
