I had a 50-60 minute connection once for SFO-DOH-CGK, and booked a transfer service only for that reason, knowing its a tight connection. Even the agent was nervous and called the gate. Boarding was nearly done, and about 1/4 of the people left by the time I got to the gate. You won't have time to freshen up, relax between the flights, and to visit the lounges.
