pageRank run 12 times slower with 0.5 compared to 0.4. What could be a reason?
Is other graph algorithms affected?

def time[A](f: => A) = {val s = System.nanoTime; val ret = f; println("time: "+(System.nanoTime-s)/1e6+"ms"); ret }

import org.graphframes._
val g = examples.Graphs.friends
val results2 = time { g.pageRank.resetProbability(0.15).maxIter(10).run() }
