Not sure what you mean by "lookups." I want to include everything between when the server sends the data, to when the page is completely generated (I'm using "rendered" to mean that). I'm trying to get a metric on the delay the user experiences. >> So that would be loadEventEnd-responseEnd, >> however I am finding that loadEventEnd is always 0 for me, even though >> I am accessing it from within a window.onload function, e.g: >> >> window.onload = function() { >> var t = performance.timing; >> var render_time = parseInt(t['loadEventEnd']) - >> parseInt(t['responseEnd']); >> } >> >> What do I have to wait for before loadEventEnd gets set? > > Stupid question, but when does the onload event occur, before or after > loadEventEnd? >From looking at https://dvcs.w3.org/hg/webperf/raw-file/tip/specs/NavigationTiming/Overview.html#processing-model it seems that that loadEventEnd gets set when the onload event completes. And from my testing it seems that window.onload fires before that > Running it in a console as I type this email, it gives me a non-zero value. Yes, in a console I see that too. But programatically, I cannot seem to capture loadEventEnd after it's set.
