Speed up resume from hibernation (suspend to disk, S4) to allow faster workspace switching and reduced bootup time

Registered by Melvil on 2006-11-05

Currently starting Ubuntu Edgy from S4 takes about thrice the time compared to Windows XP.
This can become a bit annoying when you just want to quickly start, check your calendar/mail and shutdown again.
Here is the scenario for the benchmark.

Ubuntu:
- Feisty Fawn 2006/11/05
- Memory Used: 151mb (according to gnome-system-monitor)
- Start from hibernation to GDM login: 30 seconds

Windows:
- XP SP2 with latest updates
- Memory Used: 250mb (physical, according to Task-Manager)
- Start from hibernation to login: 11 seconds

Calculating these values on a per-megabyte basis this yields to following results:
Ubuntu: 0.19 seconds/MB
WinXP: 0,044 seconds/MB

There is definately much room for imrpovement for Ubuntu
