Speeding up VCP OTG USB communication

Hi there!
I'm trying to transfer as much ASCII as possible from my STM32F4Discovery board.
Basically I'm doing this:
while (1) {
            APP_Rx_Buffer[APP_Rx_ptr_in]=APP_Rx_ptr_in;
            APP_Rx_ptr_in++;
            if(APP_Rx_ptr_in == APP_RX_DATA_SIZE)
            {
               APP_Rx_ptr_in = 0;
            }
}

Why it doesn't work? If I slow down this loop, I can get some data..
Best regards,
Tom
