I doubt you are hitting any processing bottleneck. More likely memory capacity/bandwidth and possibly flash storage speed bottlenecks. Probably on an A4 based iOS device? I agree Apple should do a better job for these older devices however they can't let the world revolve around 3 generation old platforms either. With the A5 and especially the A6 it's less of an issue because both have hit a 'good enough' point where they shouldn't be too starved on memory capacity/bandwidth unless iOS/apps dramatically change in the next 2-3 years.
