Why is it so slow to Sleep or Shutdown in El Capitan / Yosemite....? In Snow Leopard you press sleep and it is instant. I'm not talking about the screen going black, but the actual computer & hard drive stopping. Now in the newer OSX it takes atleast 30 seconds or more. The same goes for shutdown but that isn't quite as annoying as I rarely power-off the computer. Logging out can be pretty slow too. It reminds me of Windows and the constant force quit notification when shutting down. Otherwise the Operating System is quite fast.
