Hi, I have a few questions for you : We have 2 possible designs for our product. Either we expose every single feature as a separate node (and we would have up to 1000 nodes, many of them implementing the same interface), or we aggregate the features into a few "supernodes". Some people here may think the second solution is not as elegant as the first solution in some aspects. The questions : Does the DBus forwarding performance decrease when many nodes are registered to the bus ? What about the memory usage ? Is the introspection data stored for each node in the daemon itself or is it accessed on demand ? Would there be a way to make sure that nodes which have the same introspection data (same methods signature, ...) share a unique introspection data string in memory ? Thank you Jacques
