 <p>This info on the changelog is more related to the fact that before the maximum number of concurrent sockets node could handle was set to <code>5</code> (it was changeable of course) but now it is set to <code>Infinity</code> by default.</p> <p>This has nothing to do with the capacity of connexions an application can handle, that will be limited by the network's characteristics, the OS specifications, the available resources on the server, etc.</p> <p>In short, you are looking at something (the blog post) that has nothing to do with your question.</p>
