"263 HTTP requests"
Seems reasonable. bwahahaha!
Shall we discuss the number of DNS requests?
And how many of those offsite servers are using something convoluted like Amazon for DNS? (which I find is more and more prevalent thanks to AWS)
The blog author, e.g., is using Amazon for DNS.
Alas, for each and every name, this adds more than a few lookups to what could be a 1-2 request process. Amazon uses multiple levels of indirection.
This dance is not of much consequence in the case of a single name.
But in the aggregate, e.g., many names requested from one overloaded site (such as one author singles out) after another, it does add up.
This also creates a larger margin for errors (failed lookups getting retried and timing out, again and again... while the user sits and waits).
