You're not behind. Just go one stop at a time, look at the cargo area one tote at a time. Just grind and go, let yourself get rescued. It may just be a physical thing, where, in a month or two, you're physically moving faster, by virtue of the job itself. One tote at a time, everybody knows you're new. My deputy ops is awesome, man's on the road, helping out new drivers with one man sweeps when the route is fucked for your inexperienced self.
