boost asio异步和stl异步的简单对比

#include <iostream>
#include <boost/asio.hpp>
#include <boost/thread.hpp>
void print(const int data)
{
  if (data == 99999)
    std::cout << data << std::endl;
}
int main()
{
  boost::asio::io_service io_service;
  boost::asio::io_service::work work(io_service);
  UINT tm1 = GetTickCount();
  for (int i = 0;i < 100000; i++)
  {
    io_service.post(std::bind(&print, i));
  }
  UINT tm2 = GetTickCount();
  std::cout << "cost:" << tm2 - tm1 << std::endl;
  try
  {
    boost::thread([&]() {
      io_service.run();
    });
  }
  catch (...)
  {
  }
  getchar();
  return 0;
}
