Just to put things in perspective I think this might be one of the largest installations coupled with the smallest computing platform . My last information was around 250 modules totalling 1088 individual networked objects and over 1500 serviced objects in all when macros and such included. Like Vivian suggested I think the polling period will probably have little impact -already starting off with a base line of a relatively long few minutes. I am aware that you will potentially have camera handling in the near future and I can tell you that there will definitely be an additional impact from these..
A couple of things you can test: stop the network and check CPU % in this state. It should be pretty near zero but if not might suggest that the 'idle' camera objects in your database are actually not being so idle. To check this you can temporarily delete camera objects in structure view eg. on AUIs and IVC digitiser object (don't save the database after such a deletion!) and see then if the CPU usage drops. Also from this position you can visit the Tools | Network supervisor | Service Tools and Temporarily disable all network nodes. Now hit the network run button and your network will run but without communicating with any physical modules - you can think of it as simulation mode. What is the CPU usage now? You probably need to try with Cortex minimised and expanded to see if any difference in each case as I think you suggested on your set up this has a significant effect.
