My 2011 Mac mini with 16 gigabytes of ram and a Seagate enterprise 600 Pro ssd takes twice as long if not three times as long to boot up than did Mavericks.

Anybody else having this problem?

I have this issue as well. 2012 Macbook Air with SSD. I think it is the encryption on the hard drive. Maybe. When mine finishes I am going to see if it is faster after encrypt complete. If not I am going to remove the encryption. I also disabled location services but that did not make a difference.

I do not have encryption enabled on my Mac.
 
No encryption on my Mac, but boot times are identical to Mavericks.

So far, I've noticed incredibly quick shutdown/restart times. Much like pre-ML OS X.

Do you have a Solid State Drive (SSD)?
My MBA booted and was online in about 10 to 15 seconds with Mavericks. Much slower with Yosemite.
 
128 SSD / 8 Gb memory / Clean install, no upgrade and my cold boot up time is around 9 to 10 seconds and shut down is about 1 or 2 seconds.

I have Mid2012 MBA, 256 GB SSD, 4 GB RAM, about 20 to 25 seconds to boot. Progress indicator shows for about 10 seconds. It is definitely slower than Mavericks for me, by about 10 seconds

I guess that squashes my theory!
HD is still "optimizing." under the encryption settings

Maybe it the clean install, IDK.

Maybe, or do you think it may have to do with what is booting up with your system. I have only iTunes helper.
 
With my Ssd I would boot in around 5 to 8 seconds. Now its at least double.

Mine's a hybrid, actually. Yeah, I'm one of the rare few who has a Momentus XT hybrid (HHD, but with SSD "parts") installed in my late 2011 MBP. The boot time, from powerup to my account, takes about 10-13 seconds.
 
My Mba i7 mid 2013 with ssd 8gb ram would boot up in matter of seconds, 10 at most, now there's a progress bar, definitely slower but not slow per se...
 
Same here. 2009 Mac Pro with SSD and I get a progress bar and an extra 10 seconds or so. No biggie but another pimple on Yosemite's arse.
 
For anyone who's interested, below is a list of boot times for an iMac7,1 running 7 different versions of OS X.

10.4.11 = 26s
10.5.8 = 31s
10.6.8 = 32s
10.7.5 = 41s
10.8.4 = 39s
10.9.5 = 43s
10.10 = 49s

The timings are a measurement of how long it took to get from a cold boot to a usable desktop.

I used a script to do the timings (https://sourceforge.net/projects/osxcoldstart2desktoptimer/) which is better than using a stopwatch - but there's still probably a margin of error that I'm uncertain of.

As you can see, there is a gradual increase in boot times.

I'm not complaining particularly, more features seem to always equate to longer boot times. I only did the timings because our users are constantly telling us that "...the Macs are so much slower than last year". I just wanted to confirm what was happening.

The iMac 7,1 is our oldest Mac. I have a vague memory of it being a reasonably quick machine when new (late 2007) although it seems quite slow now. The test timings appear to confirm this. It is however, a good test machine since it can run every OS from 10.4 to 10.10.

The Mac involved was installed with a base OS, and no other applications. It had been initially installed with 10.10 - so the hard disk partition scheme reflected this (it contained a 10.10 recovery partition).

I've not updated our users to Yosemite yet... but probably will very soon.

There is definitely slower booting, but I am experiencing slower read access in general on my boot drive since installing Yosemite. I see this when copying files, Time Machine backups, and even accessing Quick Look data for photos. I don't know if this is related to Core Storage, though my Mac Pro is too old to support it. But something is definitely wrong there. (and yes I ran Disk Utility and repaired permissions)
