At present I'd say on average not hugely. AFAIK no-one's really worked on boot speed optimization since right after I came on board at RH: https://fedoraproject.org/wiki/Test_Day:2009-02-19 (man, it's so much harder to find test days from back when we didn't put the subject in the page name...) overall boot speed is a pretty chaotic equation, with a lot more than just the init system involved. I think it's fair to say that, all other things being equal in an ideal world, it may be possible to make things faster with systemd than with upstart, but it's by no means a given, and there are likely other things we can do that will have a more significant impact on boot speeds. We could do another such test event for F17, but to be really effective it needs buy-in from a developer in the position to understand the results and do something about it, like Lennart and Harald. -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Twitter: AdamW_Fedora | identi.ca: adamwfedora http://www.happyassassin.net -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
