I've pasted your code below, with some inline comments in it, mostly because I can't fit it all reaonsably in a comment. How are you determining that it's taking four seconds for changes to get from client1 to client2? Visual inspection?
Does this mean that Client1 & Client2 are running on the same machine (no different network latency issues to worry about)?
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
