Global : 
- Only optimize when you need to! Pixi can handle a fair amount of content off the bat.
- Be mindful of the complexity of your scene. The more objects you add the slower things will end up.
- Order can help, for example sprite / graphic / sprite / graphic is slower than sprite / sprite / graphic / graphic
- Some older mobile devices run things a little slower. passing in the option 'legacy:true' to the renderer can help with performance
- Culling, is disabled by default as its often better to do this at an application level. If you are GPU it will improve performance, if you are CPU bound - it will degrade performance

Sprites:
- Use spritesheets where possible to minimize total textures
- Sprites can be batched with up to 16 different textures (dependent on hardware)

    // Start with a temperature, in Kelvin, somewhere between 1000 and 40000.  (Other values may work,
    //  but I can't make any promises about the quality of the algorithm's estimates above 40000 K.)
