I have been extending the scenario generators, so I have often
used ns to generate topologies of several hundreds and sometimes
one or two thousand nodes *without actually running any simulation*,
and then I have also run some expensive simulations. I can say that
the topology generation takes a considerable ammount of time. There
are ways to check this. For example, just generate the topology
and view it with nam, without running the simulation (see the
topoview script in the scen-gen package) - you will see what
I mean.
