I am looking for a bit of help please, when I have iTunes running and playing music it often starts jumping and the laptop is very unresponsive. When it does this I usually have Word and Google Chrome open. I think I have figured out it is mainly when chrome and iTunes are open together, but I do not understand why this is a problem, surely the laptop is capable of this. I have attached screen shots of the performance screen to show what is happening. If I shut down iTunes I have no problems but it is not using excessive RAM I don't think.
