In my experience, a healthy Java application (after the heap size has stabilized) will have a heap utilization graph where the low points are between 50 and 75 percent. If the low points in heap utilization are consistently below 25 percent, you would be better off reducing the heap size and allowing the OS to use that memory instead. If you want to track heap utilization, JVM-Memory in the Solr dashboard is a very poor tool. Use tools like visualvm or jconsole. https://wiki.apache.org/solr/SolrPerformanceProblems#Java_Heap I need to add what I said about very low heap utilization to that wiki page. Thanks, Shawn
