The comparison was unfair it was only moving the positions of the rectangles each frame for paper.js, and two.js but for pixi.js it was redrawing them from scratch which means it had to retesselate everything every frame.

I made a PR to fix it and its much better: https://github.com/slaylines/canvas-engines-comparison/pull/...

It is still not the optimum way to do it in pixi.js but it at least matches the other examples now.
