A couple things you can try when you first create your MapNode... You can try adding more tile loading threads:

mapNode->getTerrainOptions().setConcurrency(16);

You could also try progressive mode, which forces the tiles to load in resolution order:

mapNode->getTerrainOptions().setProgressive(true);

You can also try running osgearth_imgui and opening the Network Monitor to see if you are network-limited. Good luck.
