Editor's Notes
- David – keep high level, don’t read word for word, clear up the title meaning
- David
- Renaun
- Renaun, Kailand Demo “do slow to faster”, spin it as the reason why performance is important, and the important testing across devices Do demo on more android devices,

- Renaun
- Renaun, pay attention to slowing down, add take away
- Renaun talk to Kailand , what is the display list/explain up front – add take away
- Renaun point out this is for all objects
- David
- David
- David, explain what the matrix transforms are
- David
- David, add actually code in the visual part
- David
- David Take away – here about caching leafs not parents
- David, change to do global matrix instance or reuse instance,
- David, new Matrix() change

- Renaun , talk to Kailand here!, I put timing stats into my loading phase to find out where the bottleneck was in creating objects
- Renaun , talk to Kailand here! 8000x8000 pixels, look table for hit detection,
- Set up the context about what pooling is Talk through all what I am doing in the product, just leave both memory and performance checked on Make sure to say milliseconds
- Give better context around demo and 100 ships
