Across the performance industry, the metric that's used the most is "page load time" (i.e, "window.onload" or "document complete"). But these metrics suffer from the same major drawback as page load time: they are ignorant of what content the user is most interested in on the page. Any performance metric that values all the content the same is not a good metric. The way to do this is to create custom metrics with User Timing. Sample Custom Metrics. MORE
