We study the efficiency of an improved multiboson algorithm with two flavors of Wilson fermions in a realistic physical situation $(\ensuremath{\beta}=5.60,\ensuremath{\kappa}=0.156$ on a ${16}^{3}\ifmmode\times\else\texttimes\fi{}24$ lattice). The performance of this exact algorithm is compared with that of a state-of-the-art HMC algorithm: a considerable improvement is obtained for the plaquette auto-correlation time, while the two algorithms appear similarly efficient at decorrelating the topological charge.
