Comment(by pavol_droba):

 Just curious,  VC++2008 employs quite rigorous run-time checking, which is
 sometimes enabled even in the Release mode. This checks significantly
 reduce the performance. To get a serious reading I suggest to disable all
 checks and compile in Relaase mode with maximum optimization possible. One
 example is SCL to disable it use #define _SECURE_SCL=0 or add
 _SECURE_SCL=0 into C++/Preprocessor in the project settings.

 Can you please re-run the tests using this settings?
