I would also say the title is very presumptuous; claiming to make all pages load faster is an unachievable goal & clearly an exaggeration.
All of the speedup suggestions outlined in your article can also be handled easily - easier than Rails or not, I don't know - in other languages and frameworks as well. There is nothing about any of these items that only Rails can handle - heck half of them don't even have anything to do with your choice of server-side frameworks.
The main point of your article is "How Rails can make it easy to make your pages load faster".
Looking at http://www.alexa.com/topsites for example, which of those would you think Rails could make faster?
No, it is not. This is a claim which is testable and measurable, and for reasonable assumptions, you can predictably, measurably, and in a reproducible fashion improve page load times by implementing the YSlow recommendations.
If you have the following line of code in application.rhtml:
javascript_tag "prototype", "scriptaculous", "shopping-cart", "color-picker", "mysite-functions"
and you add these 16 characters
, :cache => true
then every page on your site now loads faster.
P.S. Explanation for non-Rails users: the above code causes the five specified Javascript files to be concatenated into "all.js" the first time any page on the Rails site is rendered, and all pages load all.js rather than loading the five Javascript files. This cuts the overhead of four HTTP request/response cycles from the page. It gives an obvious, measurable impact to page load times, and plays well with another braindead easy optimization "set your HTTP server to gzip outgoing textual content (including Javascript)".
