[News.eclipse.test-and-performance] Re: What about analytical models?

I too think this is a good idea. Hyades has focused on the raw data collection
and analysis but leveraging this as heuristic data for projections and model
simulations would be a true value add. However as Mike says, we should walk
carefully and see who is willing to step and commit some resource to making this
a long term project.
