Udp sockets

Question

I need to send a large number of UDP pakets ~ 8000/s at 540bytes(header included). The problem is only capures 197 frames (the buffer size) and then my computer almost freezes. Any ideeas what's to do?
Here is the source code internal void OnReceive(IAsyncResult ar) { serverSocket.EndReceive(ar); frames++ serverSocket.BeginReceive(byteData, 0, 540, SocketFlags.None, new AsyncCallback(OnReceive), null); } why the hell can't i insert a linefeed>

I don`t really see you beginning a new asynchronous receive here is some receive callback sample I made: using System; using System.Collections.Generic; using System.Net; using System.Net.Sockets; using System.Text; using System.Threading; namespace ConsoleApplication1 { class Program { static UdpClient udp; static IPEndPoint ipe; public static void ReceiveCallback(IAsyncResult ar) { byte[] recvBytes = udp.EndReceive(ar ref ipe); Console.WriteLine({0} received {1} bytes from {2}:{3} DateTime.Now.ToString() recvBytes.Length ipe.Address ipe.Port); string str = ASCIIEncoding.ASCII.GetString(recvBytes); Console.WriteLine(\{0}\ str); if (ar.IsCompleted) { ar = udp.BeginReceive(ReceiveCallback udp); } } static void Main(string[] args) { ipe = new IPEndPoint(IPAddress.Loopback 1234); udp = new UdpClient(ipe); udp.Client.ReceiveBufferSize = 8192; udp.Client.SendBufferSize = 8192; Console.WriteLine({0} started listening on localhost:1234 DateTime.Now.ToString()); IAsyncResult ia = udp.BeginReceive(ReceiveCallback udp); while (!Console.KeyAvailable) { Thread.Sleep(1); } if (ia != null && ia.AsyncState != null && !ia.IsCompleted) { udp.EndReceive(ia ref ipe); } udp.Close(); Console.WriteLine(); Console.WriteLine({0} all done DateTime.Now.ToString()); Console.ReadKey(true); } } } maybe it helps note that when an asynchronous receive is completed you need to begin a new one and so on until the end :)
