Hello everybody !!!
Reviewing patch #7533, Rob Beezer noticed that the Graph function to
compute the distances between all the pairs of vertices in a Graph (
shortest_path_all_pairs(), written in Python ) is much slower than
computing independently the distances between all the pairs of
vertices
No answer to the main question, but just completing the timings:
sage: G=graphs.RandomGNP(300,.1)
sage: time d=[G.distance(i,j) for (i,j) in Subsets(G.vertices(),2)]
CPU times: user 3.67 s, sys: 0.00 s, total: 3.67 s
Wall time: 3.72 s
sage: time d=networkx.all_pairs_shortest_path(G)
CPU times:

You can obtain some c_grah in Sage with
cG = G.copy(implementation=c_graph)
I don't know how far the development is though.
