あなたのdllはマルチコアを活かせるdllですか？

「PythonはC++よりどれくらい遅いのか」ということを気にするOpenCVユーザーは、使っているDLLやcv2.pydのビルドの中身を気にしよう。マルチコアのCPUを使っているのに、使っているdllの中身がそれを活かせないdllになっていることはありませんか？

buildIno.cpp

#include <opencv2/core/core.hpp>
#include <iostream>

int main(int argc, const char* argv[])
{
  // ビルド情報を表示する
  std::cout << cv::getBuildInformation() << std::endl;

  return 0;
}

CMakeLists.txt

cmake_minimum_required(VERSION 2.8)
add_executable(buildInfo buildInfo.cpp)

find_package(OpenCV REQUIRED)

if(OpenCV_FOUND)
  include_directories(${OpenCV_INCLUDE_DIRS})

  target_link_libraries(buildInfo ${OpenCV_LIBS})
endif(OpenCV_FOUND)

Pythonの使用しているcv2.pydの条件は
次のようにしてわかります。
>>> import cv2
>>> print cv2.getBuildInformation()
