Performance Tests of the Kramers Equation and Boson Algorithms for Simulations of QCD

We present a performance comparison of the Kramers equation and the boson algorithms for simulations of QCD with two flavors of dynamical Wilson fermions and gauge group $SU(2)$. Results are obtained on $6^312$, $8^312$ and $16^4$ lattices. In both algorithms a number of optimizations are installed.
