&gt; 1500 is the MTU of Ethernet...<p>It&#x27;s the de-facto MTU of <i>much</i> of The Internet. Baby Jumbo (MTU &gt;1500 but &lt;9k), Jumbo (MTU ~9k), and Super Jumbo (MTU substantially larger than 9k) frames exist, and are supported by many (but -sadly- not all) Ethernet devices.<p>Edit:<p>&gt; Also with how global traffic is managed smaller packets tend to get priority...<p>Do you have a reliable citation for this? I would <i>expect</i> that core and near-core devices would handle <i>so</i> much traffic, that they <i>all</i> would be using MTUs <i>far</i> higher than 1500 bytes per frame.
