Takes a long time for my macbook pro to wake from sleep
The greyed out (and blurred) background with the progress bar indicates that your computer hibernated (as opposed to suspended) - meaning it dumps the memory state to disk, and when resuming needs to restore that memory state from disk to memory.

To check which sleep mode your computer is using run the following from a terminal:

pmset -g | grep hibernatemode


If it is 1, this would be the expected behavior. If it is 3, OS X is unable to resync the memory state from background tasks (such as time machine) and may fully restore the memory state from disk. If it is 0, the memory shouldn't have been dumped to disk during normal sleep which would indicate that it hibernated as a last resort before losing power.
