Diffusion speed in what? Assuming air, the mean free path will be several cm so collisions can be neglected in a first approximation. The rate of diffusion will then be approximately the molecular velocity v=sqrt(3kT/m).

The speed of diffusion of any odor is determined by the temperature of the air and any air currents. With perfume, it is evaporated from the skin by skin heat and travels through the air at a speed due to temperature. Warm air rises so it moves up. Any other currents will help to move it.
