How to speed up Wakeup Time from Display Off on Mac

Hi,

I would like to ask about how to setup a faster wakeup from display off.

the MAC will logout and display off when Inactive, when I press any button to wakeup the Mac , it may take a long time to show login page on screen (around 20 sec) .

I want to make it wakeup faster , do any setting in MAC for the behavir ?
