I've also gone through this process, it did take about 30 minutes in my case. That also included waiting for a TSA agent to be available to even start the process. So YMMV, perhaps based on how busy the airport is at the time.

They had me answer a series of questions about past addresses etc, it wasn't just an extra pat down in my case. After answering all the questions correctly they allowed me to continue.
