Probably a corporate machine vs personal desktop divide. My corporate windows laptop has so much security/keylogger/spyware crap that time to unlock is ridiculous.
I just timed it, my personal Mac takes 10s to the login screen and then 4 seconds to the desktop after putting in my password. My work Mac takes 3+ min. All of the endpoint monitoring stuff they put on there really takes its toll.
My windows gaming PC starts up in about 30s from a cold boot (though it's not encrypted...), so I would at least put the personal Mac and the Windows machine in the same ballpark. I couldn't have told you which one is faster without timing it. The work machine laptop is clearly noticeably slower.
