Slow wake time

Have a 2017 iMac that I upgraded from a 2011 iMac. If I am away from it for a longer period of time (say at least an hour), it seems to go into a deep sleep mode. Will click away on the key board or mouse but for a good 10-15 seconds before I can see the computer start to wake up (which I can tell because my USB audio light changes to standby mode). Once it is awoken it then goes to a light sleep mode where you can see the display is on but you have to click one more time to get from a black screen to the log in screen.

I feel like my old computer was much faster at waking up, but now I am trying to figure out if I am crazy or it just made more noises during the wake up process so I felt like it was doing more.

So my question is, is this normal behavior or is there some setting I should tweak that would enable a quicker wake time? I know on the laptops Apple has been big on a faster wake like you get on an iPad.
 
In my opinion, what you described is not normal behavior.

I have the 2017 27" iMac and as soon as I click my Trackpad 2, (after 15 mins to an hour plus) the iMac wakes right up. Even if you have a Fusion Drive, your new iMac should not be that slow to wake.

Sounds like something may be corrupt. Did you do a TimeMachine restore with the new iMac, or set up as new? What are your current "Energy Saver" settings?

It was set up as new. I don't think I changed any Energy Saving settings but I clicked reset to defaults now and it didn't look like any check boxes changed but we will see what happens going forward.
 
I've noticed this on my new 21.5" 4K iMac. if it is in sleep mode for a long time, and I click the magic keyboard or magic mouse, nothing happens. I end up having to click the power button. once this is done, I see the apple logo and the normal progress bar filling up. then I'm back to the login screen. however, even here, it takes about 20 seconds before I can use the keyboard to type in my password.

after this is done, it takes about 10-20 seconds before my magic mouse cursor appears and then I can start using the machine.

thoughts?
 
I'm guessing it's about 5-7 seconds for my 2017 Core i5 iMac with 24 GB RAM, with Sierra (upgraded old install, with a good number of applications installed). This is with Apple's PCIe SSD.

For my 2009 Core 2 Duo MacBook Pro with 4 GB RAM, with High Sierra beta (brand new install with just a few applications), it's about 1-2 seconds. This has a SATA II interface and a Samsung 840 EVO SSD.

So the machine that should be much, much, much faster, is actually much slower for wakeup. It seems the clean install makes things much faster for wakeup.

Yeah. I am sort of hoping this problem sorts itself out next week when I upgrade to High Sierra as I have scoured the forums and have not found anything definitive to diagnose or solve the problem.
 
I have the same thing with my 2017 iMac. My old one was a 2009, and as soon as I clicked something it came on. This one I click repeatedly for a while, then I get the "dark but on" screen, then another click and I can log in. It does this when "prevent my computer from sleeping when display is off" is unchecked. When it's checked, its instant, presumably because only the display is really asleep.
 
My suggestion will be different from all the others above.

DISABLE hibernation mode, and "lock" the sleep image file.

It should wake up much faster after that.

Then again, if it has a fusion drive with an HDD inside, that extra time could be a result of waiting for the HDD to spin up (in deep sleep, it has probably been "spun down" by the OS).
