Windows 8 boots up so fast...

...but takes so long to shut down. My laptop boots in 11.4 seconds, which awesome for a hybrid drive setup. Unfortunately, it takes about 30 seconds to shut down. The screen goes dark after 10 seconds, but it takes another 20 seconds for it to completely turn off. I suspect that Windows is writing the user session to the disk (hibernating) during this time for a fast start up. Has anyone else experienced this issues?
