Description

Whenever TcpConn::connect is called, a system call to get_host_name is made in order to obtain reverse resolution for the connection address, right here:

void TcpConn::connect() {
  using apache::geode::internal::chrono::duration::to_string;

  ACE_OS::signal(SIGPIPE, SIG_IGN);  // Ignore broken pipe

  LOGFINER(std::string("Connecting plain socket stream to ") +
           inetAddress_.get_host_name() + ":" +
           std::to_string(inetAddress_.get_port_number()) + " waiting " +
           to_string(timeout_));
···

get_host_name executes getnameinfo underlying and the thing is that depending on your system configuration in the case of the address not having a reverse resolution entry it might take a long period. In my case it takes 10 seconds.
