latency difference

command line pinging splitpaw.everquest2.com results in a latency of 27mslatency shown ingame is ~120ms - 200msWould appreciate any information about that inconsistancy.

<p>This is just an educated guess, but I'm going to say that the latency shown in the network stats window is the latency associated with transfering a payload larger then 4kb which you are sending via your ping test. I think it's safe to say that the client will request a larger payload then 4k. What size that payload may be, who knows...</p>

Pinging a host results in an immediate answer from the host. The latency you see in game probably includes the time to process the sent data. Not sure about that, but it sounds plausible.

Also, a ping test sending 1000 bytes gives me the same ping numbers as it does with just 32 bytes, so its  probably not due to the size of what's being sent .

Right, havent considered the packet size.packet size of 10000 bytes: ~125mspacket size of 20000 bytes: ~ 250ms But I doubt there will ever be such a large single packet, as no sane network programmer would craft such large packets as they get fragmented over the network and cause more traffic and effort than required.there are rather several tiny ones but in a much larger number sent per second (which was the cause of another problem I had before, which was packet loss as the router couldnt handle the amount of packets).
