If you are using Linux or OSX, this should work: sudo echo 1 > /proc/sys/vm/drop_caches For Windows, CacheSet seems to provide the functionality: http://technet.microsoft.com/en-us/sysinternals/bb897561.aspx To avoid any leftover from memory mapping vs. cache trickery, I stop Solr, issue the drop_caches call and start Solr again. - Toke Eskildsen
