If your js thread is busy, the resource will wait until its idle, if you face a huge resouce loding time, checkout is there any long runing task in the Main section like this. Like this profiler an anonymous function occup main js thread, so the resource only avaliable after this function excuted

Resource loading typically involves processing the received data. you could find what the app actually does for 'resource loading' phase by opening the 'Main' section (Frames, Interactions, Main -..), it would list function calls and the total time / self-time details.
