Since Bruno just began hunting bottlenecks, Yade could be useful even for 5e5 - in the current state, one iteration would take about 5 seconds (by extrapolation). > > hi, Vaclav, > is it possible that the 5 mins used for packing or sample preparation > to fill the container?

No, I was loading that file from .xml and it took that time after starting the simulation that had been already loaded. I think Janek (ping Janek ;-) ) could comment on this, the PhysicalAction containers can take a lot of time to initialize.
