同步服務端：

    boost::timer tm;    io_service is;    ip::tcp::acceptor acceptor(is, ip::tcp::endpoint(ip::tcp::v4(), 8000));    for(;;) {        ip::tcp::socket so(is);        acceptor.accept(so);        char buf[501];        error_code ec;        so.read_some(buffer(buf), ec);        buf[500] = '\0';        cout << buf << endl;        cout << "all time:"<<tm.elapsed() << endl;    }

同步用戶端：

    io_service is;    ip::tcp::socket socket(is);    ip::tcp::endpoint  ep(ip::address_v4::from_string("192.168.3.33"), 8000);    socket.connect(ep);    error_code ec;    char buff[500];    memset(buff, '9', 500);    socket.write_some(buffer(buff, 500), ec);    return NULL;

非同步服務端：

    io_service is;    ip::tcp::acceptor ac(is, ip::tcp::endpoint(ip::tcp::v4(), 8000));    boost::shared_ptr<ip::tcp::socket> psocket(new ip::tcp::socket(is));    ac.async_accept(*psocket, boost::bind(accept_f, psocket, _1));    is.run();void accept_f(boost::shared_ptr<ip::tcp::socket> pso, error_code ec){    std::cout << pso->remote_endpoint().address() << std::endl;    boost::shared_ptr<string> pstr(new string("999999999999999999999999"));    psocket->async_write_some(buffer(*pstr), boost::bind(write_f, pstr, _1, _2));}void write_f(boost::shared_ptr<std::string> pstr, error_code ec,                   size_t bytes_transferred){}
