note that all these wavefunctions have to be stored in memory ...

     kinetic-energy cutoff     =      70.0000  Ry
     charge density cutoff     =     500.0000  Ry
     cutoff for Fock operator  =     280.0000  Ry

... and that you have a rather big cutoff

     convergence has been achieved in 222 iterations

222 iterations is definitely too much
