multi picture detection

[Parisa-DolphinSoft]

Hi
I created a js project with react and three.js and arnft (jsartoolkit).
I see some problem in arnft performance (or maybe I did not understand How to use correctly)
I hope whenever you find the answer help me.
This is my email also : [email protected]

I checked this complete example also : https://github.com/webarkit/ARnft

Problems:

1. when I use multiExample (multi picture detection ) ,If I use for example 3 picture on entity list my camera load very very slowly.
