Sorry to fill up this thread, but I think I have found the problem. On my iMac I had my display sleep set to one minute, since I figured I don't need a display anyway. I believe this caused the problem. I adjusted it to Never and the awful lag seems to have stopped. It would also explain why it happened after a period of inactivity. Interestingly, this does not seem to affect my MacBook Air. So if you have an iMac and notice this problem, you may want to open System Preferences, go to Energy Saver, and check your display sleep. I'll let you know if the problem persists.
