Hi, You'll have to test because there is no general rule that works in all environments, but from testing this a while back, you will reach the point of diminishing returns at some point. You don't mention using StreamingUpdateSolrServer, so you may want to try that instead: http://lucene.apache.org/solr/api-3_6_1/org/apache/solr/client/solrj/impl/StreamingUpdateSolrServer.html
