Has anybody any information about the performances of wavefunction and
charge extrapolation (options wfc_extrapolation,
pot_extrapolation='first-order', 'second-order') in PWscf? I am wondering
if it makes sense to keep it,  in the absence of any evidence that in at
least some cases it makes the calculation faster.
