WebSep 9, 2015 · Betweenness centrality is a slow calculation. The algorithm used by networkx is O (VE) where V is the number of vertices and E the number of edges. In your case VE = 10^13. I expect importing the graph to take O (V+E) time, so if that is taking long enough that you can tell it's not instantaneous, then O (VE) is going to be painful. pit barrel cooker grate
