   It's hard to see what would make performance poor here. Could you provide more detail about what you are seeing. 
   
   One thing that will impact performance is using getObject() as opposed to get(). Again, it's hard to know what the impact of that will be without knowing the vector types, but you might find memory performance (and time performance also, if there's a lot of data), is improved by switching on vector type and using a reader that gets the value as a primitive. Getting objects every time can lead to a lot of GC overhead.
