Chiara Modenese proposed the following answer:
Hi Jessica,

I would answer that all depends on your input parameters and what you
are interested to study (small or large strains behaviour, for
instance). Tuning parameters like particles density generally helps
speeding up the computation time, e.g. by increasing your time step. You
can also try reducing the interparticle stiffness if you do not care
about the actual value of your interparticle parameters (in other words,
if they do not match with real physical parameters defined at the
interparticle level). Alternatively, you may try increase the strain
rate, making sure your solution does not vary because of that.

Happy to help you more on this issue if you have further enquires.
Cheers,
Chiara
PS1 There is some literature on the topic, have a look at the book on DEM edited by Radjai and Dubois, for instance
PS2 Do not be afraid to play with your input parameters to try making the simulation faster, but be thoughtful on the changes you make
