Why is my iMac slow after rebooting?

When I reboot my iMac, it's basically unusable for 10-15 minutes after it restarts.

I have a Late 2015 27" iMac 15 with 16 gigs of RAM and 40 gb free hard drive space on the startup drive. It runs fine, but on the occasion that things get mucked up and I need to restart, there's often something that takes forever to quit, and then when it finally restarts, I can barely do anything for 10-15 minutes — and then all of a sudden it's fine. It's running the latest version of Catalina, but I've had the same issue on previous OSs. I've run Disk Utility from Restore mode and it doesn't find anything wrong, and Googling has turned up nothing.

I have a slightly older (but faster) iMac at work running the same version of Catalina, and it never exhibits this problem.
