The SpriteBatch class is a really fast version of the DisplayObjectContainer built solely for speed, so use when you need a lot of sprites or particles. And it's extremely easy to use :

var container = new PIXI.SpriteBatch();

stage.addChild(container);

for(var i = 0; i < 100; i++) { var sprite = new PIXI.Sprite.fromImage("myImage.png"); container.addChild(sprite); } And here you have a hundred sprites that will be renderer at the speed of light
