Simulating in omnet++ takes too much time

I'm simulating a Network with more than 5000 nodes in Omnet++ 5.0 & Inet 3.4. Pure me that it takes too much time waiting.

I did simulation in Cmdenv, and added some stuffs in omnetpp.ini file like:

record-eventlog = false

vector-recording = false

scalar-recording = false

statistic-recording = false

cmdenv-performance-display = false

cmdenv-express-mode = true

But even nothing changed.

I notice that the initializing network phase takes a very very long time.

Please help me to find out!

Thank you in advance!

Someone asked a similar general question in the Omnet++ Google Group a few years ago... and received a reply https://groups.google.com/d/msg/omnetpp/LR9f8ClqwuQ/U2zgMEgi6YgJ

That can be summarized as follows:

  1. Run simulation in the command shell environment. You are already doing that.
  2. Try different GCC compiler options. Make sure you have at least -O2
  3. Consider parallelization
