Slow response during Socket.Connect

[nebiros03]

Hello everybody.
I'm currently developing a complex project that involves Sockets communication for a client/server app under microframework 4.0. I've been working on this for a year. At this time we get a first version for our product, but it needs optimization. I've checking the socket communication, and I've watched that each time I need to send a message, by calling the Socket.Connect method, it takes a long time to connect, so I've tricked the proccess to reconnect after to receive the response from the server, But I thing that it is not an ellegant way to resolve this issue, in addition that some times I get the socket blocked, having to reconnect again... what takes a long time again.
Is there any explication about why the Connect process takes me so long?
Thank you for the support.

I recommend that you try the example code for sockets provided with Microsoft NETMF SDK and take a look  at how the sockets are handled.
We did not notice that Socket.Cnnect() takes long time. On the other hand, this method has long timeout. So if there was no response from the server, expect a considerable time for this method before exiting.

Thank you for the opportune support.
Let me describe you the System.
At the server side I have a tcpListener that process the chipworkX request, sending back the required data to a random Port.
At the client side I use a NetwotkStream to Read/Write data on the chipworkX Socket.
I'm using only one socket o read/write data and a thread that continuosly check if there is Data availible on the network stream.
At this point I have some questions.
Why after I receive Data I cannot reuse the same socket to write Data?
Is there a way to keep alive the socket without having to reconnect each time I need to write on the socket?

So you mean the socket is closed as soon as you finish the transaction? I can not a certain answer. But you can forward the question to NETMF team www.netmf.com on the forum. I am pretty sure  you will get an answer from the members.
