[Bug 70858] Re: Readahead should start in the background
Interesting... Too bad ionice is in /usr/bin which automatically qualifies it as unusable...

attached are some bootcharts for released version of readahead (27 seconds) + background (22 seconds / 19 % faster) + ionice -c3 (21 seconds / another 3 % faster) ** Attachment added: "bootchart with released version of readahead" http://launchpadlibrarian.net/20598140/bootchart-intepid.png -- Readahead should start in the background https://bugs.launchpad.net/bugs/70858 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hmm, seems the contrary of: https://launchpad.net/distros/ubuntu/+source/readahead-list/+bug/59716 However, booting with readahead in the foreground (thus stalling the bootprocess), my bootime in edgy is roughly 55 seconds, while it is 47 seconds when readahead is started in the background... And a lot of people at http://www.ubuntuforums.org don't benefit from readahead in the foreground. It seems illogical that readahead can be faster in the foreground - reading ahead large files like all python libraries implicitly used by hplip/kde-guidence and all fonts loaded by X before continuing the bootprocess. -- Readahead should start in the background https://launchpad.net/bugs/70858 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
