It will keep up to the limit, and it will save caches periodically and reload them on start. But the cache needs to be populated by traffic first. If you wrote a bunch of data, enabled the row cache, and began reading you have to first wait for population of the cache prior to looking at cache locality. Note that the saving of caches is periodic and if you were constantly restarting nodes during testing maybe it never got saved with the full set of keys. > Regarding your previous question about queue size in iostat I see it ranging > from 114-300.
