Start The World. Examine tick rate... Walk away, check again each couple hours to see tick rate getting worse and eventually as below. Only a restart fixes it.
I've included before and 11 hours after shots. A screen clip of hardware use at the 11 hour mark, and logs. Can also provide world download if needed.
