Slow recovery from Sleep Mode

[Jericho14]

I have a late model 2009, 27" desktop iMac.
The browser and all software are up to date.
The computer works as good today as it did on the day I bought it.
Except.....when I awaken the iMac from the Sleep Mode, it used to come up within a few seconds, now it is taking sometimes 60-90 seconds.
Ive not added any new software or hardware for a decade.
Not a major problem, but I'm concerned that it may be indicative of some other issues with it.
Any suggestions?
TIA

Throw an SSD into it. Consider with this an OWC heat sensor kit when you change the hard drive.

I have a late 2015 2tb Fusion and I’ve notice this as well since updating to the latest Mojave’s last update 10.14.2. It is not 60 seconds but it’s far longer than it use to be.

Edit, Its not every time though, I just came to wake it up from yesterday and it was instant.

Edit, and the next morning it took 15 seconds before showing the screen open with watch
