+UIParticle has some overheads, and the batching depends on uGUI.  
 When improving performance, keep the following in mind:
-- If you are displaying a large number of the same effect, consider `Mesh Sharing` feature in [UIParticle Component](#uiparticle-component).
-  - If you don't like the uniform output, consider `Random Group` feature.

-- If you are using multiple materials, you will have more draw calls.
-  - Consider single material, atlasing the sprites, and using `Sprite` mode in the `Texture Sheet Animation` module in ParticleSystem.
