how to adjust the load of each node

I'm a newbie to starcluster. I just managed to created a 2-node
cluster based on AWS EC2. So far it is running the assigned jobs.

However, I found the total time of running my jobs in this cluster is
way slower than running all of them on one machine.

I'm suspecting the low performace is becauseI'm not using the full
capacity of each node.

Can someone let me know how to check the nodes' CPU load percentage of
each node ? How to read the load information from "qstat" ? If the
threshold is low, how can I adjust it ? Can I ask one node to accept
multiple jobs simultaneously ? Now my observation is that each node is
only taking one job at one time.
