The speed of game has been affected by the new update. It takes me minutes to open messages, there are 5-10 second delays on any typing I do, and if I try to put more then one building in a queue it takes minutes at best to accomplish it. I am finding it is faster to refresh the page then to try and do multiple actions. I have windows 7 and use internet explorer 11. To be honest the game is pretty much unplayable.
I change to chrome and it works fine. So it must be a problem with your game working with internet explorer
