Hi Francois, I think you misunderstood the question. 3 clients are connected to the same server. 1 client has a keep-alive connection and the the most part of the job. Sometimes, 2 other clients have to send or receive additional data. To keep the server load as low as possible, I'm now testing with a connection close for those 2 other clients. My questions is : would there be any speed penalty for the 2 clients that now use a connection-close instead of keep-alive. I can't see any difference here, but it's a high speed line. Maybe there is no difference at all, since the first connection (keep-alive) keeps the route open to the server. It would lower the server load since it doesn't have to send keep-alives to the other 2 clients.
