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).

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.
