Internet on my macbook pro is so slow fine on my ipad 2?

Ive noticed when browsing the web on my 2011 macbook pro 13 its very very slow sometimes it never loads the page. Ive only just noticed as I always use my ipad 2 to browse the web however after updating my macbook to lion started using it for a while and noticed the rubbish performance. I use safari and google chrome its slow on both browsers any ideas what it could be any settings I can change? As I said when browsing on my ipad 2 its lightening fast no delays so its certainly not my connection.
