Gazebo can simulate populations of robots. I am looking for 100 robots for my simulation. ARGOS simulator claims that Gazebo slows down (simulation time increases) as the robot population increases by few dozens. Did anyone tried simulating more than 100 robots using ROS-Gazebo?

There are many factors that influence the speed of simulation. Simulating many simple robots can be faster than simulating a single complex one, for example. It all depends on the models used, how the physics parameters are tuned, and the speed of the computer running the simulation.
Here's an example of 50 planes flying in simulation, each model has only a few joints, and there aren't many contacts being calculated. All robots were controlled using ROS and Ardupilot.

Here is an example with ground vehicles, I believe there were around 300 of them. Note how the simulated time is 4 times faster than real time, even with all these contacts being calculated.

Hi Louise. Thank you for the answer and showing examples.
