All Clear does is the ID check part. The actual security screening is all TSA. In the TSA lines, this is quick and never the bottleneck. The person doing the ID check actually throttles the line so that it doesn't back up in front of the X-ray belts. The Clear people are then allowed to cut this line that is ultimately waiting for the X-rays, which are the rate limiting step in the screening process. The airport (who is being paid) is arranging for Clear people to cut a line for a Federal government service that all passengers have paid equally for.
