Had to load the core.

Testing revealed approx 5x speedup in my rig vice cloud solr server.
Used the following locator config:

SOLR_LOCATOR : {
  # Name of solr collection
  collection : collection1

  # ZooKeeper ensemble
  #zkHost : "localhost:9983"
  solrHomeDir : "/homedir/solr/solr-4.8.1/example/solr"
  batchSize : 1000
}
