The branch releng/15.0 has been updated by cperciva: URL: https://cgit.FreeBSD.org/src/commit/?id=8f5eb720e2e67446fc9c10ab61d0069c356cd73b commit 8f5eb720e2e67446fc9c10ab61d0069c356cd73b Author: Colin Percival <cperciva@FreeBSD.org> AuthorDate: 2025-10-12 21:44:14 +0000 Commit: Colin Percival <cperciva@FreeBSD.org> CommitDate: 2025-10-16 20:08:05 +0000 packages: Compress in parallel The FreeBSD-base pkg repository is currrently dominated by a handful of large packages: Out of a compressed repository size of ~960 MB, about 160 MB is taken up by the FreeBSD-src package, 128 MB (on amd64) is used by the FreeBSD-kernel-generic-dbg package, and 91 MB is used by the FreeBSD-src-sys package. Consequently, running 'make packages -jN' provides less benefit than one might hope, as most of the packages finish building quickly, ultimately leaving the FreeBSD-src package building by itself for a couple minutes while all the other CPUs are idle. Pass -T${PKG_CTHREADS} to the 'pkg create' commands (with a default of -T0) in order to instruct pkg's zstd compression to use multiple threads. Testing on an EC2 r7i.48xlarge instance with -j192, this reduces the time taken by 'make packages' from 6m17s to 1m39s; package creation time itself (excluding the initial process of installing into world and kernel staging directories) dropped from 5m37s to 59s.
