The CPU time you are seeing there is of the entire map phase and the entire reduce phase... not just the function itself.
This is kind of confusing terminology because you have the map function and reduce function, which are only a portion of the map phase and reduce phase.
This is the total CPU time across all of the nodes in the cluster.
