Andrew, if you upgrade to 1.4.M06, your shell should be able to do Cypher in order to count the relationships of a node, not returning them:
start n=(1) match (n)-[r]-(x) return count(r) and try that several times to see if cold caches are initially slowing down things. or something along these lines. In the LS and Neoclipse the output and visualization will be slow for that amount of data.
