Does this also apply on Qvector?

I pass large arrays (100000x100 double) many times (around 30000 times) and cant see the difference (in execution time) between

f(QVector<QVector<double>>& _array);

f(QVector<QVector<double>>& _array);

To copy to clipboard, switch view to plain text mode 

and

f(QVector<QVector<double>> _array);

f(QVector<QVector<double>> _array);

To copy to clipboard, switch view to plain text mode 

Thanks for your time, Stefan
