Somebody made a popular series of blog posts back around 2005 or so, about how to scale up a server to handle huge numbers of TCP connections. I think he eventually got up to a million open sockets on one machine (in part by stuffing it full of Ethernet cards to get around the 16-bit limit on port numbers.) I don’t have them bookmarked, unfortunately, but they’re probably not too hard to search for. —Jens
