[Neo4j] neo4j reade with getNodeById && index.with...

[孤竹]

HI,all

       I Found something interesting, The test as  follow:

public static void main(String args[]) {
        GraphDatabaseService db = new EmbeddedGraphDatabase("testDB");
        indexService = new LuceneIndexService(db);
        Long startTime = System.currentTimeMillis();
        for(int i =0 ;i <10000;i++){
            Node node = getNodeByIndexProperty(db,String.valueOf(i));
        }
        Long endTime = System.currentTimeMillis();
        System.out.println("time = " + (endTime - startTime));
    }
    public static Node getNodeByIndexProperty(GraphDatabaseService db, String 
keyValue) {
//        Node node = indexService.getSingleNode(KEY_NAME, keyValue);
        Node node = db.getNodeById(Long.valueOf(keyValue));
        return node;
    }

When I try to use the method indexService.getSingleNode...... with 9999 times, 
It will take 2 seconds (nearly) , BY when I use db.getNodeById.... same times, 
It just take 350 millisecond . Does it mean getById is faster than use index ? 
or Does that mean the natural index is better than index if I can use it ?

thanks for your help ,and replies, that help me very much!
