Gamma point parallelization?

I'm trying to run a 48 atom job in parallel with abinit. There is
only one k-point, and no spin polarization. I've been through the
abinip tutorial, and have found very little effect using the band
parallelization, despite having 70 bands (I only got something like a
1.4 speedup on 4 processors). I've heard rumors of the FFT
parallelization: is this ready for production use, or should I just
learn to love serial jobs?

Thanks in advance for any help you can offer,
