Improving Optimization on Older Devices Help

Hi,
My game runs great on an iPhone 5, but pretty choppy on an iPad 2. Are there any grand (omni, settings), that I can alter to primarily graphics I am thinking, or any other memory holding element, that I can switch on or off etc, to reduce the cost of memory?

Thanks

I am aware of these pages and will be going over them, this weekend. However, if you have some common, easy to apply tips, please pass it on.
