Initially, perhaps, but riding such hills regularly is a pretty good way to build up leg strength (and confidence descending) to the point small hills aren't really going to slow you down much. Traffic (+ stop lights) is far and away the biggest thing that slows me down on a bike - I can average 5 k/h faster once away from heavily congested areas with frequent stops required. In my city at least those less congested areas are the hillier ones!
