I performed some calculations by using PBE0 and HSE on the same (molecular)<br>
systems, with same cutoffs, pseudopotentials, etc.<br>
There was not any (computational) difference between the two functional.<br>
Paolo (Giannozzi) suggested that FFT routines dominate the calculation weight,<br>
so that you do not find any benefit in the HSE screening wrt PBE0.<br>
Hope this helps<br>
Giuseppe<br>
