--- Comment #6 from nuria <[email protected]> --- >This does not introduce a fixed or minimum client-side delay. On the >contrary, >it sets a maximum possible delay due to logging. I understand that this change is better than blocking or 'arbitrary' delays. Let me rephrase: it introduces a delay as every page viewing is been delayed "ad minimum" by the amount of time it takes for the event to be logged (1 round trip). "Ad maximum", as you noted, the delay would be 500ms. Correct? We only have loading times for content pages (not bits domain) so we cannot provide loading times for bits but working with what we have: have in mind that time to 1st byte for one of our content pages served from cache might very well be over 500ms in some parts of the world at the 50th percentile. Even if bits is 5 times faster the event reporting time still would take ~100ms (I know, totally wild guess here, but I am trying to make the point that adding 100ms to page load time might not justify the data we are gathering). A plot we made for an unrelated project to illustrate RT times (note percentile 90, RT time is over 1 sec) https://www.mediawiki.org/wiki/Analytics/Reports/ULSFOImpact#mediaviewer/File:ResponseStart-connectStart-ASIA.png >> The preferable option I can see would be storing those events locally and >> polling as needed to report them.

If that is the case could we implement a localstorage/polling solution for browsers that support it? -- You are receiving this mail because: You are on the CC list for the bug. _______________________________________________ Wikibugs-l mailing list [email protected] https://lists.wikimedia.org/mailman/listinfo/wikibugs-l
