What does window.performance.getEntries() mean?

Question

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: http://i.stack.imgur.com/OfKtH.png. What am I missing?

Answer 1

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.
