At one time the only thing I was using that was non-default for garbage collection was turning on CMS. I had VERY bad GC pauses. I use the following settings now, and my pause problems are much better. There is very likely some other combination of settings that would do even better with Solr: http://wiki.apache.org/solr/ShawnHeisey#GC_Tuning Thanks, Shawn
