It's refreshing the repository metadata, which is mostly a network- bound operation and has little to do with the efficiency of the code. I don't know in detail how apt works, but IIRC (sorry if I'm wrong), in a previous discussion of this it's been suggested that the difference is apt doesn't refresh this data unless you explicitly ask it to, while dnf does automatically refresh it on most operations, depending on a refresh time specified in the repository configuration (this is several days for mostly-not-changing repos, but more like a few minutes or hours for update repos which change frequently). I believe there's been some discussion of ways the size of the metadata could be reduced, but that is a question of the overall design of the system, it's not to do with the quality of the code that implements the design. -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Twitter: AdamW_Fedora | identi.ca: adamwfedora http://www.happyassassin.net _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-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/devel@xxxxxxxxxxxxxxxxxxxxxxx
