Initially I thought it was just a problem with my code, but I have realized that it appears to be a bit random. I do one query with 100 results and have a problem but a query with 150 results has no problem. Is there something I should be looking for that can cause this sort of CPU spike?
Just as an FYI I am on a Macbook Pro running OS X 10.7 and AIR 3.1.
