the amount of RAM needed by the stats component for the default stats is fixed -- regardless of how many docs/values where are. So in Solr 3.x, unless you are explicitly asking for "calcDistinct" the amount of RAM is fixed. What you are probably seeing use a lot of RAM is the FieldCache -- used (and shared) under the covers for lots of things like StatsComponent, sorting, faceting, etc.... in modern versions of Solr you can use DocValues instead. -Hoss http://www.lucidworks.com/
