+     set optimization environment
+             Optimize state timeouts for one of the following network
+             environments:
+
+             aggressive
+                     Aggressively expire connections.  This can greatly reduce
+                     the memory usage of the firewall at the cost of dropping
+                     idle connections early.
+             conservative
+                     Extremely conservative settings.  Avoid dropping
+                     legitimate connections at the expense of greater memory
+                     utilization (possibly much greater on a busy network) and
+                     slightly increased processor utilization.
+             high-latency
+                     A high-latency environment (such as a satellite
+                     connection).
+             normal  A normal network environment.  Suitable for almost all
+                     networks.
