I have a slight problem where when the user plays my game for more than 20 minutes or so it begins to slow quite considerably. However I have been trying to work through the issues pretty hard as of late but still no luck. I have tried the leaks instrument and I now have that squared away, but I read at "bbum's weblog" about using the Allocations Instrument and taking heap shots. But i dont quite understand what i am looking at, could some one give me a hand with this?

My game involves users selecting words. I took a heap shot after each word was selected, but i am not too sure how exactly to read this. Is the heap Growth column what is currently running or is it was has been added to what is currenlly running?

And what is the # Persistent?

Also why is the # Persistent jump so much? Could that be my memory problem?
