I'm not very sure about that, but it could be that if you specify the nx, ny, nz variables, the pp.x makes an interpolation using the original FFT grid. This can be very slow, as also (if I well remember) specified in Doc/INPUT_PP*. Try to specify x0, e1, e2, e3 or else nothing, and maybe the original FFT grid (or a subset of it) will be used instead, this should make your calculation much faster.
