Optimize static resource fetch

    XMLWordPrintable

Details

    • atlantic

    Description

      • blueocean.js (642KB), 370 ms to load: is loaded on each page (dashboard, run details, pipeline)
      • Cache expiry for assets that never change is very low (e.g. fonts)
      • And so are most other JS files
      • If these are cached (not fetched for each page can easily save few secs)

      For details see JENKINS-38079.

            Right so the remaining issue is more about the multiple loading of blueocean.js - (is that still a valid problem?)

            michaelneale no, that should not be happening unless you hit a hard reload. It's expected that you guys out in the sticks in Aus are supposed to get the greatest benefit from this, so let us know.

            it seems a lot better on the whole, but that is subjective.
            In the ticket description, vivek mentions multiple loading of blueocean.js though ... that is what I meant

            I can only assume he was talking about the multiple If-Modified-After request. These are not happening anymore.
