I would imagine optimizing Mahout jobs are not fundamentally different from optiimizing any Hadoop job. Make sure you have optimal amount of task per node configured, as well as optimal amount of memory to prevent GC thrashing. (Iterative Mahout batches tend to create GC churn at somewhat respectable rate). When optimized correctly, individual Mahout tasks tend to be CPU bound.
Could you tell which Mahout method specifically you are talking about?
