<p dir="ltr">I think there are 2 scenarios here:</p>
<p dir="ltr">- NAT affecting performance on bandwidth increase: I have not noticed this quite much</p>
<p dir="ltr">- NAT affecting performance on concurrent user increase: This is quite valid and one of the downsides of a NATed network</p>

</div>What is interesting is that NAT has the potential to slow<br>
<span>down</span> your performance, as you scale up bandwidth.<br></blockquote><div><br></div></div><div>Is there data on this (I am not doubting <span>you just</span> that I haven't heard this being stated before)</div>

The Internet suddenly becomes slow and unusable Checks on how much traffic is being pulled down indicated the bandwidth pipe is still largely unfilled. Reboot router, Internet becomes <span>fast</span> and then gradually slows down. </div>
<div><br></div><div><br></div><div>We also faced this big time on a very large university network. We inherited it with multiple layers of NAT, 4Mbps satellite bandwidth and hundreds of sophisticated end-users. As user-base grew and their 'sophistication' (think <span>Youtube</span> video streaming not just checking email and browsing web pages) grew, we ran smack into this problem.</div>

<div><br></div><div>In Africa, I think bandwidth used to be THE constraint in many countries. As that's been solved in some places, the constraint has now shifted to number of ports available for doing NAPT.</div></div>
