That is a very good point, but it&#x27;s not the argument here: I&#x27;m responding specifically to the idea that webserver and webserver+fastcgi are &quot;technically&quot; the same speed.<p>Running two web servers (one speaking HTTP and one speaking FastCGI) is necessarily going to be slower than running one web server.<p>This should be obvious, although it might be &quot;not significantly slower&quot;, which is why I provided some real numbers from my experience to show at which point it becomes slower by an order of magnitude.<p>You might also find that it&#x27;s easier to debug one webserver than two.
