that requires more detailed analysis. what persistence manager do you use? maybe 
getting the 1000 nodes through the persistence manager takes the time. Is the 
time spent looping over the result node iterator, or is it still spent on the 
first hasNext() call? what's the exact query do you execute?

if the loop takes 10 seconds to run, you can also create a couple of thread 
dumps while the program runs. this will show you quite easily where the time is 
spent.

you have to restart the whole repository, otherwise the change won't have any 
effect.
