I remember those circumstances in one of the FPI sessions. I think it
was at Aldergrove. I'm pretty sure it was Alastair who I heard close
down for the night, after landing, when on my display he was still about
6 DME on the ILS.
I would guess that the person with the slow machine would be the one sending delayed data.
The only way to check this would be to run a normal session and hope that two aircraft are sitting on the ground watching arrivals. If an aircraft is lagging then I guess the two ground observers should see an identical amount of lag. It would be odd if one saw the aircraft taxi in a minute or so before the other ground observer.
Obviously the data being sent to controllers is different as I've never noticed ANY lag on the radar screen.

As you say, Stefan's reply was very interesting,
One thing I have been wondering about.
Say pilot 'A' has a fast machine, few TSR's running etc. and pilot 'B' has a slow machine with everything loaded up.
How would pilot A see pilot B and vice versa?
i.e. would the slow machine bring everything else 'down' the way it used to happen in the MP days (apparently).
Also it gets more complex when pilots C, D, E etc.. join in the local session.
Perhaps, when things are quite, a little experimenting might help to clarify matters.
I had honestly thought that when we were all using the one server that the lag would virtually be non existent, but Wednesday night proved the lie to that. (albeit at the end of the flying session)
