Summary
DescriptionWikipedia load time distribution (desktop and mobile web, globally, Dec 2015-Jan 2016).png
English: Distribution (i.e. frequency by number of pageviews) of waiting times for Wikipedia readers until a page from the English Wikipedia (mobile or desktop version) has completed loading. This duration is influenced by the user's connection speed - e.g. Cable vs. dialup, 2G vs. 4G -, their distance to the Wikimedia Foundation's servers, the size of the page being read, and by how well it is optimized for fast loading. (Values of loadEventEnd during Dec 22, 2015 to Jan 26, 2016; the global median was 1703 ms. See data source for more details. Caveat: no data is recorded in cases where the connection times out or the reader leaves the page before it has finished loading.)
