[SciPy-User] about scipy performance

Running the performance test of scipy presented at
 [ http://software.intel.com/en-us/articles/numpy-scipy-with-mkl/ ] I found it strange a
 decrease in the time that takes the computation for a large K value (see for instance the value of
 tm corresponding to k=192 and k=200). Does this behaviour makes sense? Is there any test suite available
 to better check the performance of a scipy installation?

 PD. the output of np.show_config() is shown below the data.
