It looks like half the boot time is consumed when switching resolutions from 800x600 to 1920x1080. It looks like this is when the boot is switching to the nVIDIA drivers. What video drivers have you installed?

Nvidia web drivers, they actually work.

Having TRIM Patch enabled with APFS can cause slow boot.
Having APFS with some SSDs causes Slow Performance.

Well thanks, i juts got what the problem is, actually there was a problem on booting with a kext that cause a "kextd stall" giving me 3 sec dalay on boot. I solved checking in verbose mode (-v) and reinstalling the kext. Thanks everyone.
