<![CDATA[Network sync]]>Hello,
I am creating two applications that use the network tools of Qt. It is a server that listens to a port and a client that connects to the server. All is fine except for one thing. When I write and read both ways there's a syncronization problem. The clients sends the info but it takes a few seconds until they are actually read from the server. The same problem appears vice versa.

Is there a way to ensure synchronization?

Thank you in advance

Go to <Ur installed Qt folder> /examples/network/fortuneclient and examples/network/fortuneServer directory

these example uses QTcpSocket for communication, try and run this application and see if that also takes the same time ?

I use the write and read functions and it takes a few seconds which is rather unacceptable. If I start a netcat conversation between the two computers communication is instant every time. The size of the data is small. Usually less than ten bytes at a time.

It does not take that much of time, whats the data size that u r communicating
