I use parallel_for from ppl.h and when I run the program from visual studio

  • 0

I use parallel_for from ppl.h and when I run the program from visual studio (2010) both debug and release version they run quite slow compared to running the executable from outside visual studio. Is there some option that I can disable, only in the release version maybe, to run the program faster inside visual studio?

    You can try running the program without the debugger being attached to it. In C++-Mode the shortcut for that is CTRL + F5.

    • If this is still slow, there may be some environment variable that is
      (not) being set when run from Visual Studio but when you run it
      outside of VS.
    • If it’s fast now, then the attached debugger probably slows your application down. If and how this can be improved
      depends on your project type, i.e. programming language, I guess.
