Would this help POV to render caustics any faster?

I ask this because I could not after all my attempts get POV-Ray to render some
caustics scene with chromatic dispersion as fast as Lux Render did (Lux uses
spectral rendering)other than that I would have been so happy to use POV because
of so many other features, but for this particular scene, the speed issue was
really too high of a bottleneck, preventing it to keep the same quality between
the two renderers.
