speed up initialisation of object page


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?

Solution

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