About the performance test:
For testing performance on devices we are using our Wandering / Local Avoidance scene, the scene is included in the Apex Path package.
To have a consistent test on all devices we reduced the numbers of agents from 256 to 128, other than that we did not do any optimization at all. The scene is grabbed out of the box and tested on the device.
The build is a developer build, so the performance could be even better if built as a production build.
The scene we have used to test performance on devices can be found as a part of the Apex Path package.
