Hi, I inserted. int on=1; setsockopt(socket.native(), IPPROTO_TCP, TCP_NODELAY, (char *)&on, sizeof(on) ); right after I open the connection. Still no change :( Tobias 2009/3/25 张亚霏 <kimi67300387@qq.com>:

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);

I'm already using blocking sockets as suggest in above document.

According to that document, you should not enocounter this problem when using blocking sockets. Probably your socket is not blocking? To make a socket blocking you should write something like this: boost::asio::socket_base::non_blocking_io command(true); socket.io_control(command); _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users
