The first thing to check is that the warning is a result of the CPU
actually being 100% busy.  If so, then the first thing that I would
try is lowering the resolution of the costmap, so that it has less
work to do.  Looking at the costmap_2d docs
(http://www.ros.org/wiki/costmap_2d), you'd want to change the
~<name>/resolution parameter (because it's expressed as meters/pixel,
you should increase it).

Lowering the tf update rate shouldn't have a significant effect.
