Getting beach ball on certain sites in Safari. No idea why. Have tried emptying cache, moving to 10.12b7 from b6, creating a new profile and hand moving assets to new profile, deleting all Application Support elements related to Safari, you name it.
Example site: https://webmail.va.gov
Originally it worked then over time just trying to get the splash screen up causes Safari to pinwheel cursor for between 2 and 3 minutes between each page update for that site. Not opening that site or any other similarly offending site offers no such issue. I can, for example, get to developer.apple.com and not see this problem. There are other sites that do the same thing.
