The Activity Monitor Memory Pressure graph will likely more easily turn yellow/red than before with 4GB installed. When it does that you may notice it also swaps to disk more often, that may give you beachballs as I assume you have a normal HDD installed which are slooow when swapping.
But if you only use it for light web browsing and email you may not notice any difference.
