This note provides a quantitative and qualitative eval- uation of the role of interconnection directionality in a general class of quadratic performance metrics for double-integrator net- works. We first develop an analysis framework that can be used to evaluate the quadratic performance metrics of networks defined over a general class of directed graphs. A comparison between systems whose directed graph Laplacians are normal and their undirected counterparts unveils an interplay between the inter- connection directionality and the control strategy that determines network performance. We show that directionality can significantly degrade performance; however well-designed feedback can exploit directionality to mitigate this degradation or even improve perfor- mance.
