Hmmm, why all those tomcats? Are they all running Solr? I'm pretty sure you'd be a lot better off simply having one indexer and one searcher on this box. Give the searcher the most resources I'd guess. In fact, you'd be even better off offloading the indexing process to a different (perhaps less po
