Performance tuning is a fun sport, but how you're keeping score matters more than you think, if winning is to have real impact. When it comes to web applications, the first mistake is start with what's the easiest to measure: server-side generation times.

In Rails, that's the almighty X-Runtime header — reported to the 6th decimal of a second, for that extra punch of authority. A clear target, easily measured, and in that safe realm of your own code to make it appear fully …
