Well, that'll be kinda self-defeating. The whole point of auto-warming
is to fill up the caches, consuming memory. Without that, searches
will be slow. So the idea of using minimal resources is really
antithetical to having these in-memory structures filled up.

You can try configuring minimal caches & etc. Or just give it
lots of memory and count on your OS to swap the pages out
if the particular core doesn't get used.
