There is an overhead for each core, but not much. You should not notice any performance degradation from the secondary tiny core. An easy way to check is to remove the extra core and see if that returns performance back to the previous level. Preferably you should do this without restarting the Solr instance as doing so affects performance temporarily until it stabilizes. - Toke Eskildsen, State and University Library, Denmark
