long boot time

Hi, after I install OS X 10.10, internet, and everything works perfectly. But I must boot from flash, and after I boot from flash, I set boot OS X... I have 2x 120GB Samsung SSD on RAID0 and the boot time is 30-45 second... Before I install OS X, I had Windows 8.1 and boot time is 5-10 second...

I just got ML going, and it seems to be working OK, once it boots. When I run it with -v, I can see a HUGE part of the time is taken up by loading TONS of kext files. What's the best way to go about only loading the appropriate ones?
