I am using GC, yes. I'll take a look at the docs about short-lived 
objects.

I've run my code through 'Instruments' and I'm not sure what to make 
of the results. I'm seeing all my fetch requests but it's not telling 
me what is taking the time. I need to work with it more and see what I 
can find.

Thanks.
