On the MBP 13" Retina all browsers (Chrome, Firefox and Safari) are running slow. Safari seems to work just a little better than others, but it is still very slow even when loading simple pages. Some pages load right away, but some take very long to load (1-2 minutes). When I use my 7 year old Toshiba laptop everything loads as fast. It is my first disappointment with newly purchased MBP. How can I fix it? Do I need to change settings or install any additional programs/updates? It is very disappointing that so powerful machine as MBP takes so long to load pages when compared to 7 year old Toshiba laptop which is on the same network.
