vb.net2010 vc++2010 배열처리속도 의견을.......

vc++2010 express
vb.net2010 express

두개의 프로그램으로 같은 내용의 배열을 처리했을때 시간이 vb.net2010 이 두배이상 빠른데 원인이 어떤건가요?

vc++2010 express

#include "stdafx.h"
#include
#include
#include
#include
using namespace std;

int _tmain(int argc, _TCHAR* argv[])
{
int* Array1 = new int[100000000];
time_t Start, End;
Start = clock();
for (int i = 0 ; i {
for (int j = 0 ; j {
Array1[j] = j;
}
End = clock();
cout }
getch();

return 0;
}
