to put this in perspective, if you look at the propagation delay in a fiber connection, the light travels on the order of 100 meters in 480ns. (speed of light in vacuum is roughly 30 meters / 100 ns, and speed is reduced by ~1/3 in fiber) The standard deviation is obviously lower in this case ;) /Rolf > 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 :) > > Marc [You can unsubscribe from this discussion group by sending a message to mailto:unsubscribe+100932...@fixprotocol.org] -- You received this message because you are subscribed to the Google Groups "Financial Information eXchange" group.
