Strategically place: | |

A good use case is to add them inline to sections of your site that are | |
above-the fold (right after the menu, right after the main story, etc) and also | |
in the onload handler for any critical above-the-fold images. | |

@bluesmoon Also, which repo is considered stable? Your fork, or lognormal, or another?
@pmeenan Out of curiosity, why is this step necessary?
if (t >= 0 && t < 3600000) {
https://gist.github.com/pmeenan/5902672#file-user-timing-rum-js-L9
Curiously enough, I left this step out, and am getting lots of IE9 responses that appear to be a timestamp, instead of the delta.
The spec says http://www.w3.org/TR/performance-timeline/#dom-performance-getentriesbytype that getEntriesByType
should always return a sequence. It seems like it would be more correct if the polyfill returned []
instead of undefined
when the type is not 'mark'. https://gist.github.com/edmund-huber/d3acd4d510d895cf860a#file-user-timing-js-L39
There is a bug in line 22:
if (performance.timing && performance.timing)
should probably be
if (w.performance.timing && w.performance.timing.navigationStart)
@jamischarles, the lognormal one is stable. RT plugin is opensource. UT isn't so much a plugin, nothing really to opensource, though I'm thinking of merging it into RT.
@bluesmoon Any chance that's open source? Or does Soasta maintain a private fork of boomerang?
