How to properly set up cache preload in Wordpress?

Question

caching

Good afternoon.
Situation: The W3 Total Cache plugin has a function to preload (warm up) the cache, but I don't fully understand how it works:

Bottom line: As I understand it, my settings say "update 100 pages every hour". But is it "update 100 pages, after 10 hours there will be 1000, and when the pages run out - go around" or "update the first 100 pages, what will you find"? :)
Question: Actually, if I have several thousand pages, how can I keep the site "warmed up" with minimal effort?
Server resources: 8gb dd3 and 6 x64 cores on Scalebound.
I would be grateful for any advice :)
