Hi,
granted, it's not a very sophisticated or scientificly relevant observation, but I thought I'd share this with you, since the live CDs are likely the first thing a new user is going to try out before he decides which Linux distribution or desktop environment he'll choose.
I measured the times it takes the current 11.3 M6 live systems to boot up in both VirtualBox (virtualbox-ose-3.1.4-106.2.i586) and qemu-kvm (kvm-0.11.0-4.5.2.i586) on my Thinkpad T61 (Intel Core2 Duo T8300@2.40GHz, 4GB RAM, running openSUSE 11.2, 32bit). I used the ISO images directly, no CD-ROM drive is involved here.
I used a stop watch to measure the time from the point at which GRUB loads the kernel until the desktop is usable and fully loaded. Both virtual machines were configured to use 1GB of RAM. Out of curiosity, I also included the latest Ubuntu 10.04 release for comparison. Can anybody repeat my observation that the GNOME live-CD is much slower than the KDE one? I would have actually expected it the other way around. What also surprised me was the difference between VirtualBox and KVM.
Product Time (qemu-kvm) Time (virtualbox) openSUSE-GNOME 11.3M6 0:02:17 0:03:45 openSUSE-KDE 11.3M6 0:01:40 0:02:50 kubuntu 10.04 (KDE) 0:01:35 0:01:59 ubuntu 10.04 (GNOME) 0:01:17 0:01:36
Anyway, I don't know if this is useful or if anybody actually cares about this aspect. From a "first impression" perspective, anything above 2:30 minutes feels like a very long time, especially if there is no visual feedback about what's going on - the GNOME bootup spends a lot of time in displaying a black screen with a busy cursor...
You haven't booted a real live cd yet: http://www.youtube.com/watch?v=Sgukjvw08xk (it's real, you can download and test it and I implemented some of the techniques used in clicfs).
Actually I do care for the boot time of the live cd, but as I'm the only one caring for anything about the live cd, it only brings very little gain. But the kubuntu live cds disable tons of services we do not disable, e.g. we're still starting akondi ;(
Greetings, Stephan
Long boot time in openSUSE it´s not surprising for me. I mentioned a similar experience (but on real hardware, no in virtual machine) in feature #308762: Remove Hal by default on opensuse 11.3. So could you disable some of services also? Do you think, that common users really need enabled something like avahi-daemon, cifs, nfs, postfix, rpcbind, sshd, etc? Advanced users can enable it additionaly, but me as a common desktop user i don´t really need this services. On my laptop, Ubuntu 10.04 starts only 8 services by default. -- S pozdravom / Best regards, Rasto -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org
