I didn't suggest to compare yade agains SDEC, but to compare yade
against pfc3d and esys-particle (for instance), using a well-defined
benchmark: a funnel with 10k,100k,1M particles for something that moves
and perhaps isotropic compression for a more-or-less static simulation.

Oh, really. I keep rewriting bad code all the time :-|

I don't buy this, if that means: we don't have to care about speed. For
research, flexibility is good, but if it is at the cost of significantly
lower speed when doing simulations, than something's wrong.
