One of the Macbook Air’s killer features is bootup time taken less than 15 seconds,it’s amazing for those windows PC users.The upcoming windows operating system ‘Windows 8’ is catch up now with fast booting time up in less than 2 seconds demonstration.Not in hibernate mode,is in times between pressing the power button and being able to use the PC.
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. Using this technique with boot gives us a significant advantage for boot times, since reading the hiberfile in and reinitializing drivers is much faster on most systems (30-70% faster on most systems we’ve tested)
This new fast startup mode will yield benefits on almost all systems, whether they have a spinning HDD or a solid state drive (SSD)
