Well, isn't that your problem then ? KeepAlive connections were introduced at a time when establishing and tearing down TCP connections were relatively expensive things to do. With modern servers however, this is less important. By setting KeepAliveTimeOut long, you essentially "block" a child (and all its resources), doing nothing but waiting for a follow-up request, for a long time after the last related request from the browser has come in, for the dubious benefit of avoiding the setup of a new connection.
