New tabs taking forever to load on my macbook pro retina mid 2015
This January I replaced my macbook pro retina display 15 inch from mid 2012 with a new macbook pro retina display 15 inch, mid 2015. In order to keep all my files and preferences, I used migration assistant and most of the time my macbook works fine. But it's starting to get really annoying that quite regularly, when I'm trying to open a new tab, on safari, it takes around 3 to 5 seconds to load. I don't know what is causing this, or if it's normal. Is there any solution or has this happened to anyone else?
MacBook Pro with Retina display, OS X El Capitan (10.11.3)
