Basically the whole post can be summed up via these choice quotes:<p><i>Overall, I disagree with his title, but I don’t disagree with his results</i> ... <i>his methodology, it’s mostly fine</i><p><i>Guy tested partial SPDY page loads, not full SPDY page loads. More specifically, he tested this case: if you upgrade your primary domain, but few of your other domains, your CDN, etc, how does SPDY perform?</i><p>(followed up with a table showing that this is a very realistic test scenario)
