<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Thank you for replying, Prof. Giannozzi. I'm using version 5.2.0, the system has 135 atoms of which 108 has U correction. I'm running it on 32 processors with 1 pool, a serial
algorithm for Linear algebra to avoid "error in Cholesky decomposition", and 1 task group.

I'm a bit surprised because the time report of the same system without electric field and with a denser Kpoint grid (2x2x2) looks like:<br>
<br>
init_run : 38.32s CPU 39.48s WALL ( 1 calls)<br>
electrons : 9042.53s CPU 9168.56s WALL ( 8 calls)<br>
update_pot : 4.99s CPU 6.13s WALL ( 7 calls)<br>
forces : 873.59s CPU 949.08s WALL ( 8 calls)<br>
stress : 3211.03s CPU 3260.70s WALL ( 8 calls)<br>
<br>
Here the forces is just a tiny fraction of the electrons time. <br>
