I thought that window.performance.getEntries() would match the number of requests according to Chromium's 'Network' tab, but that doesn't seem to be the case: .png. What am I missing?

  • And what's the question? – phts Commented May 26, 2015 at 10:32
  • perhaps cached items aren't included? redirects? – CrayonViolent Commented May 27, 2015 at 1:40
  • If somebody finds a way how to get all the loaded resources (like in network tab of devTools), I will be very thankful. – mmm Commented Nov 22, 2019 at 9:02

If your page have multiple redirections, network tab shows everything whereas performance entiries shows only the resources from last/current document. Also the entries count doesn't include your HTML/document count where network counts that too.

I would also like to refer https://stackoverflow./a/18978803's answer.

In my Case some Requests were missing, which occurred after the Page had finished loading. The Networking Tab showed all Requests, but window.performance.getEntries() only Showed those who responded to the original Page Call (and not later actions on the Page). I believe performance.getEntries() and the Resource Timing API only concern themselves with the original building of the Page.

Only taking chrome into consideration here, but the number of entries is limited. You can extend the limit by executing:

window.performace.setResourceTimingBufferSize(9999);
