    TCP or UDP? Little more details...

    Buffer your data and send as much as you can when you get the opportunity - don't wait for a client. (Let no packet go to waste...) If a client can't keep up, assume network failure and kick them. (Or reduce the data you're sending, if this becomes problematic.) Consider an ability to remove out of date data from a buffer before it is actually sent.

    Do you need details on handling multiple sockets in general? (select(), poll(), multithread, there are tons of approaches, all with pros/cons...) Since you mention Windows... select(), or WSAAsyncSelect() if you have GUI.
    long time; /* know C? */
    Unprecedented performance: Nothing ever ran this slow before.
    Any sufficiently advanced bug is indistinguishable from a feature.

    You should define your undestanding of the term "best way"
    The first 90% of a project takes 90% of the time,
    the last 10% takes the other 90% of the time.

    i can do that. Ok with sockets. Question is more connection configuration for game setup. Ie one tcp connection per player or one connection per turn then next player connection .

    Some options of consideration."best way"

    1 one turn per player. Sit and wait for each player to respond.
    2 ten turns for faster connection and one turn for slower connections.
    3 let slower connection user game piece idle while waiting for responce
    4 kick timeouted slower user.
    5 only move piece with user input.
    6 move piece based on previous input while waiting
    7 give slower player connection more armor so that when they are “picked on” by faster user with faster connection they can survive until their input comes in.
    8 deal with only one player at a time per turn then make next player connection.
    9 deal with few players at time then next group of players
    10 deal with all players tcp.
    11 best for games udp or tcp.
    12 other?

    multiple threads that copy the game state to a local buffer then send the buffer. Once the send is finished, copy the current game state and repeat. with seperate threads a slow connection player cant slow everyone else down, they will just get fewer updates.

    also look into both asyncronous send/receive as well as WaitForSingleObject() as it pertains to a socket.
    Until you can build a working general purpose reprogrammable computer out of basic components from radio shack, you are not fit to call yourself a programmer in my presence. This is cwhizard, signing off.
