What does CVX do during the period before using a solver to solve the SDP?

When I run a CVX program, it seems that actually the solving time printed by mosek is a small part compared with the preparation time of CVX. Does CVX use this time to convert matlab language to mosek model? If so, can I get the model it converted?
