If you have Nexus/GlobalEntry, you are golden as it will take you less than 5 minutes to go from airport door to security. T3 doesn't seem to have a dedicated Nexus security lane, so things can get a bit backed up even with priority stamped all over your card. But in my 25+ trips over the last 12 months from T3, I don't think I've ever waited more than 10 minutes in the security line ever. At customs, the average was 20-25 min and max was closer to an hour..which drove me to apply for my Nexus/GE and now it's a breeze.
