Very long boot time with H Sierra?

    I upgraded from Sierra to HS and now my Macbook 12" 2015 takes about 1-2 minutes to boot. I think it took about 2-3 minutes to boot earlier today.

    Normally it takes about 30 seconds after I hit the password to log in and then the desktop shows up.

    I also have an app that clears the apps disc cache at exit and this would normally take 1-2 seconds but instead takes about 15-30 seconds.

    Any idea what can be causing this disk issue? Thanks.

    My 2011 17" MPB with an SSD boots in 17 seconds. So no issues there. However, my 2010 Mac Pro, also with an SSD, now takes 47 seconds from chime to login menu. This is probably more than twice as long as on Sierra, which is very disappointing. And shutdown also seems to take much longer than on Sierra. Does anybody know the reason for this, and if it's normal or not for High Sierra? I have five internal drives and one eSATA card in the MP and I'm on 10.13.1.

    I've noticed start-up and shut-down times have lengthened considerably on my 2009 cMP after the HS upgrade.

    My clean installs all boot High Sierra quickly.

    Well, except for my 2010 iMac, because that one has a platter hard drive, and it was a slow booster in Sierra too.

    So, that’s makes four SSD based Macs that boot HS quickly. Two of them are APFS and two of them are HFS+.
