Hi Ferdinand,

euTcp4u can handle many concurrent connections but isn't very good 
at accepting new connections when speed is an issue.

Tcp4u is a very good library except for this one issue.  
Im not saying my wrapper is good!!! just that the C library is 
good :) 

The problem occurs when the server program accepts a new connection. 
It is a "blocking" call meaning no other communications will occur
until it times out (min. timeout period = 1 second).  Considering 
that 99% of the time no new connections will be waiting it makes the 
server progrtam very slow.

If your game is like Doom or Quake (I'm showing my age!!) where no 
action takes place until all competitors are connected then there is
no problem (euTcp4u will work well under these conditions).
Also if it's a logic based game (ie speed is not a major issue) then
euTcp4u again will work well. 

If you want to make a game where players can come and go (i.e connect 
& re-join) while the game is running (and speed is important) then
euTcp4u is not a good choice.

Along with the other suggestions people have mentioned you might also
like to look at my wrapper for Libnet (euLibnet).
I haven't tested this over the net but can't see why it wouldn't work.
euLibnet is based on Libnet which is a games based communications
library. It has a function which checks to see if a new connection
is waiting without having to actually wait.
There should also be a demo multi-client / server chat program which
demonstrates how to a server program can serve multiple clients.

So ... what type of game are you writing?
(I've been away for the last week working and I don't think I saw any
details of the game itself!)
