Oscillator Start up time

I notice that, using a ST92F150, with a 4 MHz crystal, when I exit from Stop Mode the first instruction is executed after about 10 ms. This is not the same thing declared in the datasheet (max 5 ms).

Can you help me to fasten this behaviour? I need to be fast in order to acknowledge a message received from CAN bus. Many thanks.

This problem may arise due to the fact that after exiting the stop mode the internal clock frequency is reduced to 2 Mhz
