We have examined the mean first passage time () for a particle driven by colored non-Gaussian noise. As we depart from the Gaussian behavior, the decreases regularly to a limiting value, i.e., the barrier crossing rate can be accelerated to a limiting value by increasing the non-Gaussianity of the noise. For the non-Gaussian noise driven process increases linearly with increasing damping constant or noise correlation time. But this increasing behavior is almost exponential in nature for the Gaussian noise driven process.
