"Coefficient to multiply speed system" in relation to execution time

in DualSPHysics v4.4
Hi,
I ran a simulation, in which particles were getting excluded so I increased the value of "Coefficient to multiply speed system" but now generation of each part is taking much longer time.

Is there any relation between this parameter and execution time ?

    @Alex, Can you clear this one for me ?

    Speed of sound, Cs, is computed as shown in page 15-16of XML_GUIDE_v4.4.pdf

    On the other hand, in the page 131 of XML_GUIDE_v4.4.pdf:
    - initial time step is defined as h/C
    - you can also see the equation to compute variable time step, dependent on the value of Cs
