How can I further optimize the intial loading time of my SAPUI5 App?

Hey guys,

I am using the Web IDE to develop an SAPUI5 app. I tried to implement all the advice about optimizing the performance from the SAPUI5 docs I could find (e.g. asynchronous module loading, see red square below). But when I build and run my app in the Web IDE, it still needs more than 7 seconds to load:

Is there a way to further improve the loading time?

Thanks in advance

Lucas
