Scalability Question

I am doing some test of Vertica scalability. First, to test two nodes cluster and then three nodes. However, I noticed that two-node cluster is faster than three-node cluster. What is more, the message "insufficient memory..." appears, only in the three nodes cluster.However, all the nodes are the same. What is the problem?
