Safari and spinning wheel

Hi guys,

For the last week or so when using Safari everything has slowed down. If I click a link, if I go to type something in the search bar, if I begin to scroll, the spinning wheel comes up for a few seconds slowing down what ever it is I was trying to do.

I'm using the latest version of Safari on a late 2009 Mac Pro. Two months ago I also done a full clean install of El Capitan. Any ideas why this would be happening all of a sudden?

 

Hi mate, no plugins at all. This is something that just started happening one day out of nowhere!

 

Yup. Pretty much all the time!
