regex performance java vs c++11

I am learning regex in c++ and java. So i did a performance test on c++11 regex and java regex with same expression and same no of inputs. Strangely java regex is faster than c++11 regex. There is something wrong in my code. Pls correct me

Java code:

import java.util.regex.*;

public class Main {
    private final static int MAX = 1_000_000;
    public static void main(String[] args) {
        long start = System.currentTimeMillis();
        Pattern p = Pattern.compile("^[\\w._]+@\\w+\\.[a-zA-Z]+$");
        for (int i = 0; i < MAX; i++) {
            System.out.println(p.matcher("abcd_ed123.t12y@haha.com").matches());
        }
        long end = System.currentTimeMillis();
        System.out.print(end-start);
    }
}

C++ code:

#include <iostream>
#include <Windows.h>
#include <regex>

using namespace std;

int main()
{
    long long start = GetTickCount64();
    regex pat("^[\\w._]+@\\w+\\.[a-zA-Z]+$");
    for (long i = 0; i < 1000000; i++) {
        cout << regex_match("abcd_ed123.t12y@haha.com", pat) << endl;
    }
    long long end = GetTickCount64();
    cout << end - start;
    return 0;
}

Performance:

Java -> 1003ms
C++  -> 124360ms
