Performance Debugging

You can use the built in tools in the browser to find issues, such as long running JavaScript functions. Note that debugging can be harder for apps built with JavaScript frameworks that include a compile step.

Your tasks

• Run a performance test (core web vitals) and document the results. To get realistic load times, use the deployed version of your app and not a locally hosted one.
• Analyse the result. Is your web app fast enough? If not, use the tooling to find causes and decide on measures.
  • Run another performance test and document the new results.
  • Analyse the differences. Did your measures have any impact?
