My code gives me packets loss:
Qt Code: 
  1. clientConnection = new QTcpSocket(this);   
  2.     tcpServer = new QTcpServer();
  3.     connect(tcpServer, SIGNAL(newConnection()), this, SLOT(newConnect()));
  4.  
  5. void frmMain::newConnect()
  6. {
  7.     clientConnection = tcpServer->nextPendingConnection();    
  8.  
  9.     connect(clientConnection, SIGNAL(readyRead()),
  10.             this, SLOT(receivePkg()));   
  11.  
  12.     connect(clientConnection, SIGNAL(disconnected()),
  13.             clientConnection, SLOT(deleteLater()));            
  14. }
  15.  
  16. void frmMain::receivePkg()
  17. {
  18.     read_size = clientConnection->read(buf_c, READ_BUF_SIZE);

Tell me how to create TCP-server:

-received 10+ packets (1 packet length = 200+ bytes) per 1 ms
-received packets for 10+ min
-without packets loss

May be I have to use another thread and set priority to thread.

Give me server code, please.
