you can optimize the documentCache by setting maxSize to some decent value, like 2000. Also configure some meaningful warming queries in the solrconfig. When increasing the cache size, monitor the RAM usage, as that can starting increasing as well. Do you / would you need to use filter queries? Those can speed up search as well through the usage of filterCache.
