[SciPy-User] What is the complexity of scipy.sparse.linalg.eigsh

Hi, all
      Recently I am using scipy.sparse.linalg.eigsh to compute K smallest
eigenvalues(and their eigenvectors), but I have no idea how fast the
function  runs. I know it uses ARPACK's implicitly restarted Lanczos Method,
but I found no such information on ARPACK's official site.

thanks
