For performance reasons, be careful if you set the total number of steps
to a high number. For example, if you're iterating over a large number of
items, consider setting the redraw frequency to a higher value by calling
:method:`Symfony\\Component\\Console\\Helper\\ProgressHelper::setRedrawFrequency`,
:method:`Symfony\\Component\\Console\\Helper\\ProgressBar::setRedrawFrequency`,
so it updates on only some iterations::

$progress->start($output, 50000);
$progress = new ProgressBar($output, 50000);
$progress->start();

// update every 100 iterations
$progress->setRedrawFrequency(100);
