Hello! Thanks for sharing your feedback regarding the range performance. Indeed as you partition things like agent ports heavily this can be detrimental.
We have looked at this in the past, and the right thing to do is indeed to use the interval set in Stout. That being said, the reason we haven't done so yet is that the Resources object currently exposes the protobuf used to store the data internally. The approach we would like to take is to introduce a c++ based resource and resources object that is unversion (used only internally). Primarily Mpark, BenM, XuJYan, and I have been thinking about how to tackle this larger task. Please bring this up at the next community sync so we can see how we might cut this into manageable chunks.
