MemUsage how much is too much?

I ma running around 1300 to 1500. I really don’t even know the unit, I am assuming KB. I have noticed a significant performance drop from 1300 to 1500. What is everyone getting for this? How is it possible to lower it? Is this what is affecting performance?

My texture memory is around 14mb by the way. Testing on iphone 4

Thanks for your help.
