10-second Fast Boot times in Windows 8

Windows 8 will be delivering a hybrid shutdown and boot process, that merges the traditional cold boot approach with resume-from-hibernate functionality, reducing startup time by 30% to 70% and resulting in 10-second boot times for new PCs with solid state disks (SSD).

This new fast startup mode will yield benefits on almost all systems, whether they have a spinning HDD or a solid state drive (SSD), but for newer systems with fast SSDs it is downright amazing.

On the official Windows 8 blog, Windows program management director Gabe Aul said;

a hybrid cold boot and resume feature closes user-facing sessions but keeps kernel processes in hibernation mode. This allows PCs to power down and use “effectively zero” power but start up far more quickly than Windows 7 computers.

Aul further stated the key difference for Windows 8: “as in Windows 7, we close the user sessions, but instead of closing the kernel session, we hibernate it. Compared to a full hibernate, which includes a lot of memory pages in use by apps, session 0 hibernation data is much smaller, which takes substantially less time to write to disk.”

It’s faster because resuming the hibernated system session is comparatively less work than doing a full system initialization, but it’s also faster because we added a new multi-phase resume capability, which is able to use all of the cores in a multi-core system in parallel, to split the work of reading from the hiberfile and decompressing the contents, Aul concludes.
