The disclosed computer-implemented method may include (1) receiving a set of control performance values and a set of modified performance values, (2) determining a set of comparative performance values based on the set of control performance values and the set of modified performance values, (3) generating a call graph based on the set of comparative performance values, the call graph including a set of nodes, each node corresponding to a function, the function corresponding to a particular comparative performance value included in the set of comparative performance values, and (b) a set of edges connecting the nodes based on relationships between the nodes, (4) weighting each node in accordance with the comparative performance value corresponding to the node, and (5) displaying the call graph via a user interface in accordance with the weighting of each node. Various other methods, systems, and computer-readable media are also disclosed.
