Or hibernate?
At least on my system hibernate takes as much time as a reboot.
btw this is a very fundamental property of hibernate. You need to do all disk IO to get the system state to disk. And then at resume, you need to do all disk IO to get the state from disk again. That's twice ;)
This is compounded by the property that a hibernate tends to flush at least half the disk cache (it has to, to get space to work in), which you then need to page right back in, so even when you're back, the first minute or two sucks badly.
I suspect you will always be able to boot faster than you can hibernate+resume.
I have very different experience. For example comparable (from grub going away to KDE + my bunch of default apps running and usable) numbers just taken from the desktop box in front of which I'm right now (AMD64 3200, 2G RAM, SATA, F-9 x86_64 KDE):
- shutdown: 28 sec
- fresh boot: 66 sec
see this is the problem; this can be 5 to 10 seconds, and should be. that's the point of this discussion
