You have Apps open in the background (probably multiple apps)

To remediate that, press the POWER button to re-lock the phone, then press the POWER button (again) to unlock the phone (then prolly close some of the apps).

Alternatively, it could be an app displaying on the lockscreen, causing the delay.

Remove any Live Lockscreen type Apps.

Turn on Kids Corner and enable it... Then put the phone to sleep and wake it again. Turn Kids Corner off. (A weird workaround, but many swear by it.)

As MDK22 said, close any Apps running in the background. Since 8.1 Apps do not always close automatically by pressing Back button to exit. Hold down the Back button to get the card view and tap the X icon in the upper right of each card to close it.

You may want to do periodic Soft Resets as well. Hold the Volume Down + Power buttons until the phone vibrates and reboots. You won't loose any data that way.
