> As the size of input data increases, building Graph eat much processing time via GraphLoader.edgeListFile() or RDD transformations.
> APIs to save Graph as a object file is useful for those cases.
> The operations are currently slow because of the default serializer (Java serialization), so efficient serialization is of future work.
