Sending files over TCP/ .NET SSLStream is slow/not working

Question

Im writing an Server/Client Application which works with SSL(over SSLStream), which has to do many things(not only file receiving/sending). Currently, It works

Answer 1

I'd give a try of gzip compress before/after the network. From my experience, it helps. I'd say some code like this could help :

using(GZipStream stream = new GZipStream(sslStream, CompressionMode.Compress)) 
{
    stream.Write(...);
    stream.Flush();
    stream.Close();
}

Warning : It may interfer with SSL if the Flush is not done. and it will need some tests... and I didn't try to compile the code.
