<p>This last graph shows that the <em>parallel_hash_map</em> is slightly slower especially for smaller table sizes. For a reason not obvious to me (maybe better memory locality), the speeds of the <em>parallel_hash_map</em> and <em>flat_hash_map</em> are essentially undistinguishable for larger map sizes (&gt; 80 million values).</p>
