Oh that's good to hear!

Good.

Well, you configure exactly what "warming" means (e.g., tell it which
queries to run).  But this doesn't mean the query results are cached: this
process just warms up the OS's IO buffer caches. When you then run the same
query later, it still must re-run all the query processing, it's just that
the pages should be "hot" from the OS and we don't have to wait for disks
to seek to those pages ...
