Hi Guys,
The Piwik issue for page load performance references the Navigation-Timing spec but it doesn't specify exactly which Nav Timing value is used nor why that one was chosen.
My assumption is that it's the "ResponseEnd" value (as shown on the timeline diagram in the Nav Timing Spec here) https://dvcs.w3.org/hg/webperf/raw-file/tip/specs/NavigationTiming/Overview.html#processing-model
Most other "Real User Monitoring (RUM)" solutions tend to use the LoadEventEnd value (e.g. Google Analytics) as it gives a value closer to the end-user experience of the loaded page.
I'm curious as to why the ResponseEnd value was chosen, rather than the value which would allow more direct comparison's across RUM products.
cheers,
Steve
