Hi, This will depend on types of queries, access patterns and what the data look like. Could you provide some more information on what the data look like, specifically relationships traversed and properties loaded for a query?
Regarding adding another machine to an already active cluster it is easy. Just configure it (assign an id and point it to the cluster) then startup it up. This will trigger replication of data to the new machine and once that is done it will be available.
