giraph.numInputThreads execution time for "input superstep" it's the same using 1 or 8 threads, how this can be possible?

I'm doing BFS search through the Wikipedia (spanish edition) site. I converted the [dump][1] into a file that could be read with Giraph. Using 1 worker, a file of 1 GB took 492 seconds. I executed Giraph with this command: /home/hadoop/bin/yarn jar /home/hadoop/giraph/giraph.jar
