We present the results of the study of quantum efficiency and gain of Visible Light Photon Counters (VLPC) at high counting rates, expected in their application as readout detectors of the scintillating fiber tracker in the Do/ detector. At a projected maximum rate of 10{center_dot}10{sup 6} photoelectrons/sec, the VLPC quantum efficiency only decreases to 97{percent} of its maximum value. Since other applications may involve higher counting rates, we present data up to rates of 90{center_dot}10{sup 6} photoelectrons/sec. {copyright} {ital 1998 American Institute of Physics.}
