I have a random graph created with=A0

4=
00 vertices

1200 edges

for which I am ob=
taining the transitive closure using=A0

Transitive=
Closure.INSTANCE.closeSimpleDirectedGraph(graph);

this takes over four minutes. I've attached a=
screenshot of visualvm which shows this self time:

org.jgrapht.graph.AbstractBaseGraph$DirectedSpecifics.getEdge() | 92.61042 | 214.290 ms (92,6%) | 214.290 ms |

Is this performance normal? (4 minutes for a=
graph of this size)

Many thanks,

David
