Hi all!

I am in possession of a macbook pro 15 Inch late 2012 i7 model with superdrive running OSX yosemite 10.10.3. And I am having the problem of a slow sleeping macbook when I close the lid. It differs of course, some times 5 seconds, some times 10 seconds. But the idea of me waiting before its sleeping (you know, when the lid-light is flashing) is just not what I'm used to (when I had a macbook some years ago).

I have been trying alot, like disabling hibernation and such. Nog nothing really worked. I hope any of you have a solution? Here are my logs:

PS. I'm also running windows in bootcamp. And when I close the lid in windows, it kinda sleeps instantly. ---------

Doesnt explain why its almost instant in windows tho. It should be able to go faster
Different operating system handles sleep/hibernation differently then OS X does. Windows does some things better then OS X and OS X does some (a lot) things better then Windows.

I'd say the performance of OS X going into sleep is not out of the ordinary. Try unplugging all USB products and remove any apps that might be running in the background (such as istat menus or other similar apps) that could be delaying the sleep request.

Putting on my moderation hat, I edited your OP, there was too much whit space that impacted reading the post.

Does it really matter?? 10 secs is hardly going to be a problem, it is probably just shutting down a few background programs sorting out TRIM etc.

As for windows shutting down instantly, everytime I boot out of bootcamp into osx I have to wait 10 minutes for it to download a slew of updates, now that is annoying.....

Just a shot in the dark here, but sometimes slow sleep and/or shutdown issues can be solved simply by rebooting in safe mode and then restarting normally. I had a similar problem recently and that did the trick for me.
