## 3.4. What performances to expect ?

This depends radically on your options choice. You have to keep
in mind that the tree algorithm is fast and the energy algorithm
slow. Drawing trees, mixed tree-loop structures with loops up to
3 nodes (or with bigger loops but the "Fast" option
also on) will be fast -- less than 1 second for 100,000 nodes --
as no energy optimization is required. When the energy algorithm
is used, the computational cost depends on the maximum number of
steps allowed (field "Max Nb of Steps") and the number
of nodes (about one second for the AntSimulation graph [60
nodes] with Max Nb of Steps = 25,000).
