We have a solr instance running on a 4 CPU box. Sometimes, we send a query to our solr server and it take up 100% of one CPU and > 60% of memory. I assume that if we send another query request, solr should be able to use another idling CPU. However, it is not the case. Using top, I only see one cpu is busy, and the client side just gets stucked.
Is solr 3.6 able to do multithreading to process requests? Ming-
