Psi has been running like a dog since the update. Slow to load, slow to do anything, do one thing like Demand from a farming village, then generally have to refresh browser before it will process the next task.
Using IE9, installed Chrome, but still the same. Making playing very difficult.
After reading another post, I have installed Firefox, and so far the game is responding much better. Hoping this may help developers find the problem and fix the problem other browsers are experiencing.
