We noticed when loading our very large sets into Maya that the time taken to select objects in the viewport was taking upto a minute. Running the code through vtune, we identified that the most significant bottleneck was simply a result of the call to UsdImagingEngine::SetSelected. Removing these two calls returned us to an interactive selection speed within the Maya viewport.
