[ros-users] how fast can roscpp timers run?

Hello-

I'm writing a node that will be my servo loop for a robot. In a previous
implementation the timing consisted of checking the system microsecond
counter and calling the servo update each millisecond.

Can I use ros::Rate or ros::Timer to get anywhere near 1 kHz rate? If not,
what is the practical lower limit for these?

Thanks,
