I was more than happy with 2 seconds or less on my i7. But I'm flabbergasted by 3 seconds on my old Core 2 Duo, a six-year old PC.
Booting time depends on the reading speed of the Hard Drive, that's why SSDs are the fastest.
My laptop is an i7 with a 512GB SSD. I haven't updated it yet, so I'd like to take notes of the actual boot time and after the upgrade, so I'll ask: WHERE exactly do I find the booting times?
Inquiring minds would like to know.
