Well, with some newer systemd features (that we'll probably enable for fedora in f15 [1]) we are currently measuring bootups of < 7s (and a pid < 500) from grub to panel showing up on the screen. (that's kay's X300 with ssd on a modified opensuse), 5s or so are actually spent in gnome of those. there's definitely room to improve things in gnome. some things we are starting are kinda obvious candidates to make faster. Not going to name names here, but some things show up kinda badly in bootchart, and we are talking to the folks maintaining that to figure out what can be improved here. In the long run I want to make gnome use systemd for session management, so that the same parallelization techniques we use for system boot can be used for session startup as well. We aren't there yet though and we need to figure a few things out before we go there. That's material for f15/f16. > What's the best method to measure what's taking most of that time? bootchart. Lennart Footnotes: [1] We wrote C replacements for all remaining shell scripts in the boot and in shutdown, with the exception of LVM, DM, iSCSI and NFS stuff, which are shell orgies. But then again, neither of these features really matter for laptops where fast booting is most important. The mount/fsck stuff in C is not entirely complete yet, but we are working to get the necessary work done in util-linux-ng. Note that all of this will show up in f15 only. -- Lennart Poettering - Red Hat, Inc. -- desktop mailing list desktop@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/desktop
