Making One Object Move, both players see it fine, but very slow.

Question

Hi there,
I am simply trying to send one object (movieClip) move from the left side of the stage to the right side. I am able to accomplish this by using the following very simple code:
/////////////////////////////CODE///////////////////////////////////////////////////////// ///////////////////////////////////////////////////////////////////
//PRESSING RIGHT, MAKING BOX MOVE
public function pressingRightMakingBoxMove(e:KeyboardEvent) {
          box.x += 3;
          moveBox.sender = netGroup.convertPeerIDToGroupAddress(netConnection.nearID);
          moveBox.user = "" + netConnection.nearID;
          moveBox.xx = box.x;
     netGroup.post(moveBox);
public function netStatus(event:NetStatusEvent) {
     switch(event.info.code){
          case "NetConnection.Connect.Success":
               setupGroup();
          break;
          case "NetGroup.Posting.Notify":
               receiveBoxMovement(event.info.message);
          break;
public function receiveBoxMovement(moveBox:Object):void{
      box.x = moveBox.xx;
////////////////////////////////////////////////////////////////////////////////////////// ENDCODE//////////////////////////////////////////////////////////////
It works fine, the box moves on both screens, but you can obviously tell there is latency. Should I be sending movements through an Object? Perhaps there is a quicker way, sending it through strings or text? Definitely not acceptable over UDP.
Thank you

NetGroup.post() may have significant latency, and postings may arrive in a different order than they are made.  it is not intended for time-critical communication.
to get the lowest latency (and most efficient transmission) for N:N communication (including 1:1), you should use the 1:1 P2P APIs (NetStream.DIRECT_CONNECTIONS and explicit peerIDs) and be sure NetStream.bufferTime=0.  it sounds like this is the most appropriate for your application.
for 1:N or M:N (M << N, N > 4) communication, you should use P2P multicast.  but P2P multicast may also have significant delays, especially while starting up.
