I just recently updated to the latest version of the iOS, it had been waiting for a while. Ever since, it seems to me that Safari is slower. I use it principally at home with my wifi and I don't think it's changed. Are there any settings I can change to improve this? I went into setting for safari and under advanced I found a page called "Website Data." There's a list of websites ordered by amount of data stored, with google being the biggest. What kind of data is this? Cookies, etc? My only options are to leave it alone or to "Remove all Website Data." Can I safely do that?
