If I want to add many ImageLayers with large data (600MB) to the map, how can I make them load and render faster? Can I use osgearth_cache, and how do I use it in osgearth 3.5? please help me.

Building overviews will help you to load them faster.

Yes, overviews and then keep scrolling down on that page for tilesets. Overviews should help alot.
