try native WSA API "setsockopt" with the TCP_NODELAY option.
if it still does not work, there may be something wrong with your windows xp. or debug the asio

Hi Igor,

thanks for your reply.
I guess you mean setting non_blocking_io to false.
Tried to enter those lines, but still have no change:
 boost::asio::socket_base::non_blocking_io command(false);
 socket.io_control(command);
