Hi, Andrew. In general, this scenario (1 million+ relationships on a node) can be slow, but usually only the first time you access the node. If you're only accessing the node once in a session, then yes, it will seem sluggish. The Neoclipse issue is probably a combination of two issues: the first is lazily loading the node information the first time, and the second is the visual rendering of all those relationships.

Some of these nodes are highly connected to other nodes. For example I may have a single node with 1M+ relationships. A good analogy is a population that has a "lives-in" relationship to a state. Now the problem... Both neoclipse or neo4j-shell are terribly slow when working with these nodes. In the shell I would expect a `cd <node-id>` to be very fast, much like selecting via a rowid in a standard DB. Instead, I usually see several seconds delay. Doing a `ls` takes so long that I usually have to just kill the process. In fact `ls` never outputs anything which is odd since I would expect it to "stream" the output as it found it. I have very similar performance issues with neoclipse. I am using Neo4j 1.3 embedded on Ubuntu 10.04 with 4GB of RAM. Disclaimer, I am new to Neo4j.
