I do physics simulations, and can easily reach those times with a similar amount of input. And that is with highly optimized Fortran code. But yeah, a comparison with a pure Java or C++ implementation would have been great, both in terms of speed and LOC. However, in the "real world", there usually isn't time for such silly things.
