Double check that you have build NS-3/ndnSIM in optimized mode. Implementation of CalculateRoutes internally uses Dijkstra algorithm from Boost graph library (which is known to be extremely slow in debug mode). It should be a problem for this number of prefixes and nodes.
If still fails, you can compute all routes and prefixes offline and install them directly using FibHelper.
