Too long Waiting (TTFB) SAPUI5 Application resources and WerbService requests

Hello,

I was hoping someone could shed some light on why I see such long wait times when my UI5 application loads or calls OData WebServices. Below are 2 pics I took with ChromeDev and IEDev Tools of a WebService with expand (GET_EXPANDED_ENTITYSET).

There are also other resources ($metadata, view.js/controller.js files, multiple library-preload.json calls etc) and they also have like 90% wait time although the size is marginal like 5-100KB.


I look at multiple resources on OData and Gateway performance. I applied expand and batch on the gateway size. The OData suggestions like using top, select, etc I also applied where was necessary.

Hopefully someone can explain what is causing this much Waiting (TTFB) time.
