plotting - StreamPlot slow in version 10


In version, 10 StreamPlot seems to calculate many more points along each streamline than necessary, compared to version 7.


For example, from Mathematica documentation, the command


Block[{k = 0}, 

  StreamPlot[{-1 - x^2 + y, 1 + x - y^2}, {x, -3, 3}, {y, -3, 3}, 
    EvaluationMonitor :> k++]; k]

gives 184 points in version 7 and 3592 points in version 10. I could not find an option that reduces the number of points calculated. For the complicated function I am trying to plot, it makes more than a factor of 10 difference in speed.
