what is the ros gazebo sim time to real time conversion?
If I have ros melodic and I have a .world file which has realtimeupdate_rate of 1000. what is that value in camparison to real time? is it faster, slower, the same? what's the conversion here?

The upper bound on Real Time Factor is calculated by max_step_size * real_time_update_rate. The default values are 0.001 and 1000, which means gazebo will run in real time (=1.0) if your cpu is strong enough. This value can be used to intentionally slow down the simulation, or to permit the simulation to run faster than real time.

@Mike Scheutzow So if max_step_size*real_time_update_rate=3, that means the simulation is 3 times faster than real time?

Yes, but only if your cpu can deliver it.

@Mike Scheutzow Do I have to change publishing and subscriber rates if I try to make sim time faster?
