Booting Fedora 8 Test 3 vs openSUSE 10.3
Boot time: 35s
Incredible speed, I must admit. Time to look at Fedora.
Fedora 8 Test 3 - Default Installation - SELinux off
Boot time: 73s
Default Installtion, SELinux turned off. Wow, that's disappointing for the average Desktop user. Let see, why it is so slow.
Fedora 8 Test 3 - Same Services - SELinux off
Boot time: 46s
Turning off all the services, which are not started by default on the openSUSE, the boot time is nearly comparable now.
The following services are only started:
Fedora 8 Test 3 - Same Services - SELinux off - No rhgb
Boot time: 38s
Switching off rhgb saves 8s. Wow, that is much, compared to the whole boot process without the kernel time.
Fedora 8 Test 3 - Same Services - SELinux off - No rhgb - prcsys
Boot time: 34s
By installing prcsys, adding missing LSB Headers to the services, it is now less boot time than openSUSE. Hurray! :-)
Fedora 8 Test 3 - Same Services - SELinux off - No rhgb - prcsys - No Floppy module
Boot time: 32s
Removing /etc/sysconfig/modules/udev-stw.modules, which basically only loads the floppy module, because floppies are not autoloaded just saved me 2 seconds. I have no floppy on my machine, so that was only probing on my machine. Time to think of another mechanism of loading this module or not.
alias pnp:dPNP0700 floppy
This may do the trick in modprobe.conf. Maybe that should be a modalias in the floppy module.
Fedora 8 Test 3 - Same Services - SELinux on - No rhgb - prcsys - No Floppy module
Boot time: 37s
To see how much SELinux would slow down, I turned selinux on, relabled and rebooted.
For the reference, I uploaded the Machine Profile to Smolt
