how to create a ui with the best performance for gearvr in unity

I remeber in previous unity versions people often said : do not use
unity ui to create your ui for mobile. At that time I used a well know
plugin. Now I am creating a ui for gearvr. I started with the vr
examples, then did some test using unity ui and then using simple 3d
models. I find that performance of unity ui is not that good. I wonder
what are people using for ui for gearvr? The real issue here is
performance on mobile. Some ideas please?

We use Unity's UI system in a number of our Gear VR apps. We blogged recently about best practices including here: https://developer.oculus.com/blog/unitys-ui-system-in-vr. There are a few hazards, such as overdraw, inefficient batching, and excessive rebuilding of state due to small changes such as alpha or parent transforms. A lot of the same performance guidelines from the following blog post apply to Unity's UI system: https://developer.oculus.com/blog/squeezing-performance-out-of-your-unity-gear-vr-game.
