From: Denys Vlasenko on gitlab.com https://gitlab.com/cki-project/kernel-ark/-/merge_requests/2254#note_1249068590 "-n 1" will spawn one "xz" per every module. This incurs some startup costs (fork+exec+library loading). How about "-n 16", so that each xz process compresses 16 modules, decreasing startup costs by more than 90%? rhel7 and rhel8 already use this approach. _______________________________________________ kernel mailing list -- kernel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to kernel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/kernel@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
