:-)
When we will have time and resources. Athens has been in a usable state only until recently, when Igor made his tutorial.
We are using Athens and we will continue to do so. More and more Athens will become the base of Roassal. It is just that it takes time.

Over the last weeks, Roassal went through a major optimization process. Roassal has pretty much all the optimization that ZVMT has (the library of Emmanuel, from INRIA). More has to be done I agree.
By the way, if the Synectique crew (or anyone else) find some particular situations that are judged as too slow, then we will make sure the slowdown get properly removed.

For the moment, Roassal's performance is better than that of Mondrian and that suffices us. In the meantime, what we can achieve with Athens are modern-looking apps. And the screenshots prove that. and If there is a gain of performance, that's a plus for us so that we prepare ourselves for huge graphs.

the problem with huge graph is that you get lost.
We should just use them to bench roassal.

Yes they are. And then there is also the fact that humans might not be able to reason about the complex graphs with several thousand nodes. So, I think in that case we need to understand the use-cases that people may come up with.

Most of the time, the problem that we are confronted with graphs of software is to find a tree from a particular node: tracing all the dependent nodes of a root and ignoring reverse links, if any. That eliminates a lot of noise. We did some experimentation with Mathieu and we got simpler, more meaningful radial graphs. I'll try to share images when I have some time to breath.

It is still early for me to know. In a couple of weeks I will let you know
