The inclusion of fermionic loops contribution in Numerical Stochastic Perturbation Theory (NSPT) h;t~ a nice feature: it does not cost so much (provided only that an FFT can be implemented in a fairly efficient, way). Focusing on Lattice SU(3), we report on the performance of the current implementat

## Introducing fermionic loops contributions in Numerical Stochastic Perturbation Theory was mainly motivated by the proposal to compute 2-3 loops for renormalization constants (and improvement coefficients). This is feasible because the computational overhead of unquenching NSPT is by far lower t
