Slow to function after sleep

Anyone familiar with why it can take a couple of minutes for my old windows to function after sleep. I don’t recall having this issue before changing my DE to look like Mac using one of the online tutorials with Latte.

This state will hover for 2 minutes after a long sleep sessions in which time other parts of the OS works fine. My CPU utilization is in the single digits, so if it is a computational issue, then maybe we could parallelize the start up from sleep.
