Paul overstated the general importance of the scriptlet work. As I said above, it will affect the RPM transactions. Will Woods has numbers on the actual performance gains that I'm sure he'll share on this thread at some point. I said above "I'm not sure how much that will save in the *whole* compose process" and I meant that. I'm not advocating that we postpone F31 solely for these changes. At the same time, let's be careful not to slip into a "perfect is the enemy of good" situation where we start critiquing individual solutions as not having enough of an effect. _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org
