Subject: Re: [opensuse-factory] 11.3 M6 live CDs - bootup time comparison

granted, it's not a very sophisticated or scientificly relevant
but I thought I'd share this with you, since
the live CDs are likely the
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
both VirtualBox (virtualbox-ose-3.1.4-106.2.i586)
(kvm-0.11.0-4.5.2.i586) on my Thinkpad T61 (Intel Core2 Duo
RAM, running openSUSE 11.2, 32bit). I used the
ISO images directly, no
drive is involved here.
I used a stop watch to measure the time from the point at which GRUB
kernel until the desktop is usable and fully
loaded. Both virtual
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
that the GNOME live-CD is much slower than the
KDE one? I would have
expected it the other way around. What also
surprised me was the
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
aspect. From a "first impression"
perspective, anything above 2:30
feels like a very long time, especially if there
is no visual feedback
what's going on - the GNOME bootup spends a
lot of time in displaying a
screen with a busy cursor...
I did comparison in VMware on my wife´s hardware.
Intel Core2 duo E7500 - 2,93Ghz, 4GB RAM, runnig Microsoft Windows XP
32bit with Service Pack 3.
The ISO images were used directly, virtual machine had 1GB RAM.
ubuntu 10.04 - 00:00:57 (i couldn´t believe it, but it´s true)
openSUSE-GNOME 11.3M6 - 00:02:21
openSUSE-KDE 11.3M6 - 00:01:39
I can confirm in openSUSE GNOME´s case a lot of time in displaying a
black screen with a busy cursor.
In openSUSE KDE´s case the time would be shorter (around 00:01:19), but
still appears bnc# 582375 - An error occured during the startup of the
Akonadi server, which stucks desktop for a while (around 20 seconds).
Tested factory build 0646 yesterday and no progress for Gnome. Still Gnome bootup spends a
lot of time in displaying with black screen and busy cursor. And on istalled system also.
