Quick and SLOW.....
The last time I connected T-5 to T-3 (Spring 2008) it literally took me 20 minutes from the time they opened the door until I was clearing security at T-3 (I only had carry-on baggage; was in Row 21 onthe 763; travel on an American Passport; and we came into M-9, which maybe the closest gate to the arrivals hall).
On previous trips, whoever, it has taken me anywhere from 45-90 minutes to make the connection. I suspect that this is far more normal than my last trip, and others here (judging on what they wrote) may think that even my 45 minute transfers were quick
