Long delay before sleep

Question

My Mac Pro when going to sleep take a few minutes or longer until I actually hear the thing click and power down.  The screen shuts right off and the power light pulses like normal as soon as sleep is selected, but the system is still doing something.  It won't wake back up until I hear the click and the fans shut off.
If I hit a key while it's in the processes, it'll sit there until I hear it power down and immidiatly wakes back up, so I know it's not going into deep sleep.  I've check for stuff stuck in the print queue and it's blank. 
I'm not an expert on terminal stuff, but I can follow instruction if there's thing I can check.  I just don't know where to begin.
Also, I noticed this started right after installing OS 10.8.  I never had this problem with 10.7.x.

Triple-click anywhere in the line below to select it:
pmset -g | grep hibernatemode
Copy the selected text to the Clipboard (command-C).
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V).
