<p>This really hits my bs meter big time. I can't see how
nat'ing is going to cause a 40% performance hit during
connections. The article also mentions http2 (and later
v3) which definitely make big improvements so I'm
suspecting that the author is conflating them.</p>

<p>Still really thin with details of why. At least this says that
they are NAT'ing v4 at *their* edge. But 99% of the lag of filling
your newsfeed is their backend and transport, not connection times
so who knows what they are actually measuring. Most NAT'ing is
done at the consumer end by your home router in any case. <br>
