Hi Lisa,
you can throttle physics by adding an <upateRate> tag to the physics block.
For example, see this
file<
https://code.ros.org/svn/ros-pkg/stacks/simulator_gazebo/tags/cturtle/gazebo_worlds/worlds/empty_throttled.world>
<physics:ode>
...
<updateRate>200</updateRate>
</physics:ode>
if time step size is 1ms, throttling at 200 steps/second effectively
throttles simulation down to .2X real-time.
you can further reduce cpu load by disabling the simulator gui by providing
the '-g' flag when starting gazebo. For example, see attached launch
script.
