I am experiencing the slow wake problem on my 2009 4,1 Mac Pro. I did not have the problem with Lion.
Wake takes 40 seconds whereas booting from the off state takes about 15 seconds. (SSD boot drive)
When I say slow wake, I mean the desktop is there, and I can move the mouse cursor but apps are beach balled and you can't lanch any new apps.
It might be related to Time Machine because it will wake normally with Time Machine disabled. I proceeded to do a repair on my TM drive and wakes were good for about 5 days, and just today they became slow again. My TM drive is internal.
Another strange problem that has started since the ML upgade is that about 15 seconds after wake the mouse cursor jumps to the upper left corner of the screen. It does it every time the machine wakes regardless of whether it's normal or slow.

Yes, I've just posted a question about this issue on the MacBook Pro forum. Only occurs if I sleep by closing lid - then screen is monetarily "awake" then back to black for several seconds.

I'm having the exact same problems on my brand new Retina Macbook Pro. Back on Lion my computer would wake from sleep mode before i was even able to lift the lid all the way up, now on Mountain lion it usually takes between 10-15 seconds for the screen to turn on. And an additional 5 seconds for the keyboard and touchpad to become active. The things I have tried are turning off icloud and power nap but it doesn't seem to have any effect. Im worried about doing a fresh install of the os because i dont want to lose any data and honestly it is not a deal breaking problem it is just extremely frustrating. I wish apple would come out and acknowledge the slow boot problem but if not i just hope the have some sort of update in the pipeline.

Well I spoke too soon when I thought I had solved the issue.It soon came back.In the end I down loaded from Apple store again but during the day and without allowing the iMac to be interupted.So far all my problems seem to be cured.

On my late 2011 MacBook Pro the slow wake-up definitely seems to be connected to Bluetooth. I'd got into the habit of turning off my BT keyboard and mouse AFTER closing the lid on the MBP - I know they use little power if they're inactive but it just seems like good practice. If I turn them off before shutting the MBP, or leave them on, wake-up is instantaneous.

My rMBP is doing this as well. Very annoying. It's very odd in that I can see and move my cursor almost instantly, but the cursor is on a black screen. Sometimes even this takes a while to come, but all together it can take 15-20 seconds to wake from sleep.

I have the base 2.3/8/256 rBMP.
With lion, I COULD have few bugs like slow reboot or wake, but since I upgraded to ML, it's another world of pain.
1) I could rock all day on my mac with at least 7 hours of use, now I'm lucky if I can get 5 hours out of it.
2) The wake from sleep is incredibly slow, more than 5 secondes (it was 1 seconde under Lion).
3) The adapter can get very very very hot, never noticed it before ML.
4) It's taking millenias to boot and shut down.
I will grab my LION usb Key and put go back to 7-hours battery land!

I tried uninstalling anything that I thought might be causing either of the two problems I was experiencing (slow wake / mouse cursor jumping to upper left after wake) and nothing made any difference so I decided to try a clean install.
I starting by using Carbon Copy Cloner to clone my boot drive to a spare drive. I then erased my boot drive and installed ML. I used Migration Assistant to restore the user home directories from the clone. I did not restore applications or settings. I next started re-installing devices and applications a few at a time and then testing for recurrence of either problem. This process has taken a few days since I didn't work at it continuously. I now have everything that I want on my Mac Pro installed and It's working just fine, no issues. Wake is just as fast as it was on Lion or SL but I do find the boot time and shutdown is a bit longer on ML, I can live with that.

In follow up to my earlier post where I said turning off power nap solved the problem for me, I am seeing slow wake from sleep again.
From all the posts here I think this must be a pretty wide spread problem that hopefully will be resolved in the next ML software update.

I'm on an iMac running Mountain Lion and suffering the same issue.
iMacs don't appear to have a Power Nap option in Energy Saver so, unless it's somewhere else on iMacs, that can be ruled out.
I've tried going in and out of sleep using the power button, or Sleep menu item, with Activity Monitor open to see if if there's anything obvious that's bottling up. What's interesting is that every time it wakes up a process called "ReportCrash" appears at the top (when sorted by %CPU in descending size)

Ihave an iMac 27" (mid 2010) and upgraded from SL to ML two weeks ago. Same issue - very slow to wake on keyboard click and mouse also had to be clicked to respond.
Was hoping for an Apple update to fix the issue but yesterday decided to call the Apple Care helpdesk - so that they could earn some of the dollars I had spent on signing up for it. Was stepped through a hard boot:
- Shut down machine
- Unplug main power cord from monitor for 10 seconds
- Turn on using power button and immediately hold down Command+Option+R+P keys
- Continue holding this key combination for three full cycles of the start up "chime"
Wake up time is now back to same instantaneous response as prior to ML upgrade. Not sure if this "fix" will work for everyone having the issue but might be worth a try.

I also did the pram reset on my early 2009 MacPro but it did not help. It's great that it worked for you. The sledgehammer re-install approach I used is still workng for me.

I'm running the latest beta of 10.8.1 and still now changes.. I get still hangs on wake up...

It's definitely to do with Bluetooth on my MBP - and, as far as I can make out ONLY Bluetooth. If I switch my BT mouse or keyboard off after sleeeping the MBP, wake up takes ages - if I leave them on, wake up is instantaneous.

+1 on the same issue, plus the "inexorable black screen after logging in from sleep" one.
Beginning to feel the benefits of ML were illusory... all these bugs are messing with getting actual work done.
