Pre-Indexing the database

Hi,
I'm using "indexing" in Neo4j, Tinkerpop3.0.0.M5. I followed the example in documentation:
g.getBaseGraph().index().getNodeAutoIndexer().startAutoIndexingProperty('name')
g.getBaseGraph().index().getNodeAutoIndexer().setEnabled(true)

after I made the DB, first time that I accessed to DB, it's slow, but after that, apparently it uses the indices which is perfect. (I guess!!)
I want also the first time access to be fast (using index). Is there any way that I can save the indices (or pre-index DB)?
what would be the best way?

Thanks
