Nothing is wrong. TCP is a stream oriented protocol, not a datagram
oriented protocol. You can increase the likelihood that data will
be sent by disabling the Nagle algorithm on the socket (TCP_NODELAY).
See "How do I use TCP_NODELAY":
http://www.unixguide.net/network/socketfaq/2.16.shtml and also
See also "How can I force a socket to send the data in its buffer?"
