IPad screen mirroring performance

I have tried screen mirroring on an ipad using the code from:

The problem is that it is extremely slo开发者_运维问答w and bad performance (e.g. on a cross fade animation). I have tried various refresh rates but without any luck.

Am I doing something wrong or is this generally slow on ipads?

It looks like the technique it uses is resource intensive. You need to wind the mirroring framerate way down (e.g. 5 fps was fine for my needs). You won't see smooth animations on the external screen.
