It's taken me anything from an hour to a walk-up to clear security there. That airport seems to be the biggest crapshoot of all of them. I would plan on two hours from the time you walk through the door.
What I saw the other night was that lines to check bags were long, lines for security were manageable. But that's one night of many, and I've also had times that the lines at the ticket counters were fairly short but lines for security stretched halfway across the terminal.
