Increasing Simulator Speed

[DL-Thompson]

I'm trying to increase the simulator speed so I can run faster simulations. I start to see strange problems when I get above a 20x speed up.

For example, at 25x speed up, before I even send commands to launch the ardrone, it vibrates along the ground moving. Once in the air, the movements it performs don't match what commands I am sending it. I suspect maybe Gazebo can't render the drone at those speeds, but data collected also show things aren't working quite right.

I'm trying to figure out if it's possible to increase the speed more. I was hoping someone here had looked into this previously and could offer some suggestions, or could suggest where to start looking. Thanks.
