win_ros service call problems. it's req/res speed is very slow.

edit

Hi, This is Injun Park from korea(sout)

I am not good at speaking English. I want you to understand my situation^^.

Anyway, since one month ago, I have been developed robot software with win_ros. I think almost of all items in win_ros are good. but only one thing is not.

in topic case(publish/subscription), speed performance is very good. it is over 100Hz.

but service server and client communication's speed is very slow. Req/Res frequency is lower than 10Hz.

To solve this problem, I tested some cases.

1. I launched roscore on the windows and I launched service server on the windows system.

   -> windows CPP client(MSVC) is versy slow. (under 10hz)

   -> Linux CPP client is good (over 100Hz)

   -> windows Java client is good (Over 100Hz)

as a result, only cpp client version in windows(MSVC version) is too slow.

why the win_ros service/client speed is so slow..?

Has anyone had a similar problem or have any idea what I may be missing?

below code is my testing code of msvc service client.

#include "stdafx.h"
#include <ros/ros.h>
#include <custom_msgs\HelloDude.h>

int main(int argc, char **argv)
{
  ros::init(argc, argv, "client");

  ros::spinOnce();
  ros::NodeHandle n;
  ros::ServiceClient client = n.serviceClient<custom_msgs::HelloDude>("dude_service");
  //ros::ServiceClient client2 = n.serviceClient<custom_msgs::HelloDude>(

  custom_msgs::HelloDude srv;
  srv.request.greeting = "my testing hello";


  //beginner_tutorials::AddTwoInts srv;
  ros::service::waitForService("dude_service");
  ros::Time begin, end;
  for(int i = 0; i < 50; i++) {
      begin = ros::Time::now();
      if (client.call(srv))
      {
          ROS_INFO("Sum: %s",srv.response.dude.Dude.c_str());
      }
      else
      {
        ROS_ERROR("Failed to call service add_two_ints");
        return 1;
      }
      end = ros::Time::now();
      ROS_INFO("ellapsed : %f\n", end.toSec() - begin.toSec());

  }

  return 0;
}

many thanks. Injun Park
