speed up initialisation of object page

Question

We are developing a worklist application for Purchase orders. Upon clicking an entry in the table, the user will be navigated to the object view. The issue here is that when the application loads the first time, the resources haven't been loaded yet. The object page contains a fair amount of controls and the first time a user opens the page, it takes a very long time (5-6sec). After that, performance is okay.

Any idea on how to improve performance the first time or how to load the object page (or controls) beforehand?

Check the network tab in your browser's dev tools and see if there are any libraries that are not preloaded but fetched synchronously on-demand. A similar issue and the solution can be seen here: How to load sap.ui.comp.smarttable.SmartTable faster?
Make sure that the debug mode is turned off.
Follow the performance guidelines.

Pre-loading your libraries in the application's <head> improves startUp performance, using data-sap-ui-libs

<head>
  <meta http-equiv="X-UA-Compatible" content="IE=edge">
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0" />
  <title>Page</title>
  <script src='https://sapui5.hana.ondemand.com/resources/sap-ui-core.js' 
  data-sap-ui-libs='sap.m, sap.ui.layout,...' 
  data-sap-ui-preload="async">
  </script>
</head>
