These two patches add multi-threaded features to RPM to speed up the do_package_write_rpm task.
Specifically: 1) Multi-threaded xz compressor is used instead of default single-threaded gz. This has the most dramatic effect when a recipe produces a smaller number of large-sized packages. 2) Packages creation is run in multiple threads via thread pools. This is most beneficial when a recipe produces a large amount of small packages. Some not very scientific benchmarks for time and .rpm sizes (time is measured for do_package_write_rpm tasks only): webkitgtk before: 9m22s 1550M after: 1m50s 858M glibc-locale before: 3m2s 125M after: 40s 56M glibc before: 56s 54M after: 23s 38M perl before: 1m19s 63M after: 55s 42M python3 before: 40s 38M after: 28s 24M The following changes since commit bd063fa288b49b6e3ea77982d0ccc46610feb1ad: tune-mips32*.inc: use consistent comments across all three .inc files (2017-05-30 10:15:20 +0100) are available in the git repository at: git://git.yoctoproject.org/poky-contrib akanavin/parallel-rpm http://git.yoctoproject.org/cgit.cgi/poky-contrib/log/?h=akanavin/parallel-rpm Alexander Kanavin (2): package_rpm.bbclass: use multithreaded xz compression rpm: run binary package generation via thread pools meta/classes/package_rpm.bbclass | 2 + ...y-package-building-into-a-separate-functi.patch | 83 ++++++++ ...-binary-package-creation-via-thread-pools.patch | 137 +++++++++++++ ...c-make-operations-over-string-pools-threa.patch | 209 +++++++++++++++++++ ...c-remove-static-local-variables-from-buil.patch | 227 +++++++++++++++++++++ meta/recipes-devtools/rpm/rpm_git.bb | 4 + 6 files changed, 662 insertions(+) create mode 100644 meta/recipes-devtools/rpm/files/0001-Split-binary-package-building-into-a-separate-functi.patch create mode 100644 meta/recipes-devtools/rpm/files/0002-Run-binary-package-creation-via-thread-pools.patch create mode 100644 meta/recipes-devtools/rpm/files/0003-rpmstrpool.c-make-operations-over-string-pools-threa.patch create mode 100644 meta/recipes-devtools/rpm/files/0004-build-pack.c-remove-static-local-variables-from-buil.patch -- 2.11.0 -- _______________________________________________ Openembedded-core mailing list Openembedded-core@lists.openembedded.org http://lists.openembedded.org/mailman/listinfo/openembedded-core
