      Description

      Just like JENKINS-40932 we want to combine some files together to improve the browsers parallelise requests (we do too many requests - see the Waterfall report).

      These JS files should be concatinated into a single resource and served to the browser together:

      • react-router
      • react-redux
      • reselect
      • keymirror
      • redux-thunk
      • immutable

      This awesome tool provides some insight into what can be optimised (page speed + yslow + waterfall):

      https://gtmetrix.com/reports/ci.blueocean.io/ijzy6djd
      You can see from this, having fewer http requests wil allow the browser to do less "waterfall loading".

      Once we have this, we can revaluate on hi and low latency connections (low latency things are much worse than that tool shows, about 10x slower for cold load).
