Here are some actual numbers from our system in production for Eurex and Xetra:
The total time from the end of the incoming multicast packet to the start of the output packet: 480ns for the whole packet with a standard deviation of around 200ns.
This includes the multicast stack, the FAST decoding, the order-book processing and reconstruction, the output generation and the output multicast stack.
CME will be similar.
So yes, FAST is fast :)
