Using UEFI!! I need on my Laptop 12sec from SLEEP Mode and 36sec. from Hibernating Mode with normal BIOS and normal HDD! That's 4 times faster than on my desktop with 8 HDD's and an 990FX BIOS, while later needs the most of that time! Both, Laptop and Desktop still OK for me and I wouldn't use SSD's because of it's high cost and to be easy damaged (in Thailand)!
I didn't use the W10 IP for production, just for testing!! Still works most of the time an Windows 8.1 Pro! For normal work I'll will use the final of Windows 10, nothing up front!
UEFI + GTP i think is faster in my Win 8.1 works Very fast and it was really impressive..10-12 sec's i think and i use HDD...
that's we can't use OS not in RTM period on real machine or in real work testing on VM for now and some old school Laptop
On my desktop I use 4 different OS'es while on the Laptop 3!! On Desktop, while boot, I use BIOS Boot Manager for to chose what HDD/OS i like to start and do on Laptop the same. That 3 HDD'd on Laptop are 1 fixed internal while 2 in removable special cases in DVD Slot. Easy 'game'!
my fossil takes around 6 seconds with ssd but i have problem with 1 hdd now its longer i have custom made bios also.
