Skip unnecessary auto-adjustments of caches

Auto-adjusting the caches is an expensive operation
that could also occupy a considerable amount of extra

Re-building a cache that is already tuned would waste
precious resources and would not communicate effectively
whether a config change is needed or not.

Show only the config changes needed and rebuild only
the caches that need adjusting, leaving everything else
