Chrono:problems on runtime

hello everyone,

I am running a case with around 1000 DEM particles(diameter of the sphere=1cm. dp=0.02cm,simulate time: 1s) I know chrono is much more robust but it takes a lot time(about two day). The runtime seems a little unreasonable. I wonder is there any way to speed up?

I changed the distancedp from 0.5 to 0.1. But it did't reduce the runtime. Is there any tricks I can use?

Thanks in advance
