posted July 2, 2003 8:27 PM I am trying to create a server that can handle hundreds of connections (not all at once but at the 50/sec or so mentioned on the product details. So I created the below code to connect multiple clients to a server that does nothing but read any client input. The first issue I had was the connections would be refused if I set the threading.sleep too low (i.e. 200 ms). Shouldn't it be able to handle many connections/second? I should be able to go down to 20ms which would be 50 connections/second right? The second issue I had was that I had to manually adjust the # of threads the CLR allows to be able to create 100 connections. Why does the control use threadpools rather than regular threads which would be unlimited? What is a better approch to do this? Thanks for any answers and help! Client side: Public Sub main() Dim x(100) As Dart.PowerTCP.SslSockets.Tcp Dim i As Integer For i = 0 To 100 x(i) = New Dart.PowerTCP.SslSockets.Tcp Threading.Thread.Sleep(500) x(i).Connect("zitsponti", 10000) Console.WriteLine(i) Next While 4 = 4 Application.DoEvents() End While End Sub Server side: Private Sub Server1_Connection(ByVal sender As Object, ByVal e As Dart.PowerTCP.SslSockets.ConnectionEventArgs) Handles Server1.Connection Try Do While (e.Tcp.Connected) ' This is true until client closes the connection. Dim s As String = e.Tcp.Receive().ToString() 'e.Tcp.Send(s) Console.WriteLine(e.Tcp.RemoteEndPoint.Address.ToString & ":" & s) Loop Catch ex As Exception ' just eat any exceptions End Try End Sub |
