Performance for the most part is determined by the area under the curve. You can look at the green line for the turbo mod in the graph above and tell it's the fastest model because of this. The Bowtech Equilizer cam will look more like the turbo mod curve than the others. It reaches 328 in it's fastest configuration, so it has to have considerable area under the draw force curve to accomplish this. The "smoothness" is reflected in "rounding" the curve off as it approaches the dwell and also as it drops into the valley. A silky smooth draw most closely resembles a parabola (red), and the fastest, harshest FDC would look similar to a mesa (black).

Actaul draw force curves on actual bows, are a compromise and blend of these two to reach the desired shooting characteristics (smoothness vs. performance)

In a nut shell: anything you hack of the black to make it look more like the red will cost you speed but smooth things out.
