Device:            tps   Blk_read/s   Blk_wrtn/s   Blk_read   Blk_wrtn
sda1              1.43        33.72        60.85  129287651  233314088

It is surely not saturated by I/O. %iowait is less than 1.0.

The view computation is running from more than 5 hours and I would
like to see the view server use all the available cores and it will be
even better it if is possible add more nodes to assist the view
