That boottime must be a joke for a ssd. I did bootchart tests a while ago with a 40 gb ssd and got 5s to kdm. even with a few years only 1 tb hd with 1 extra partition additional to / mounted i only need 31 s (which kdm autologin), checked with this in .kde/Autostart:Code:cat /proc/uptime > ~/uptime.txt
note that was an untuned install without swap enabled. adding swap is a boot performance killer - the bigger it is, the slower it boots:
A current kanotix testimage booted via USB 2 (!!!) on my i7-2600 needs about 27s till full kde4 desktop is displayed (manually stopped). Why would somebody need an ssd to beat 44s boottimeLast edited by Kano; 18 November 2011, 10:49 AM.

We know that i7's are fast, no matter what OS you throw at them. But what about those old comps that millions of people use?
Do they benefit from Linux or what?
I'm more interested in those benchmarks than state-of-the-art-computer ones.

I don't see the point in testing the boot speed for Fedora and OpenSUSE. They're not concentrating on boot speeds.
If you want some interesting results, try Exherbo/Gentoo systemd vs Ubuntu Upstart. Preferably Exherbo since its scripts were written from scratch with systemd in mind.
Generate a kernel/initrd and make sure both systems have the same services running.

This is to be expected, considering I don't believe any of the init scripts were converted to native systemd services for 12.1. This was done since there wasn't enough time to test both the new init system and rewriting and testing all the init scripts. I think this was a good decision and allows a seamless two-step change. First ensure the new init system didn't break anything and allow those to use the old init system as a fallback. Once that has gotten more testing, in 12.2 update the init scripts to native systemd services and hopefully will see some boot speed increases.
Also, just because it doesn't boot faster doesn't mean systemd doesn't offer other useful features.

openSUSE 12.1 Boot Performance
Phoronix: openSUSE 12.1 Boot Performance
While yesterday I put out openSUSE 12.1 benchmarks for those interested in the performance of this updated Linux distribution, questions have arose about the boot performance, in particular due to openSUSE moving towards systemd and making other advancements...
