Loading.ReadObject High CPU Spike

Hi all,

I am Currently making a app with quite satisficated UI. I have done my animations in after effects and Turned them into an image sequence and animated with unity’s MECANIM animator.

I am having an issue when I run an animation of a massive CPU Spike, reducing my frames to around 3.

Looking at the Profiler79% of the cpu goes to Loading.Readobject.

I have never done any 2D animation in unity before and belived that it wouldnt be an issue. Can somebody please help, or sujest a different way of animating.

if you can print some code about your animation and image sequence,it is better for help.
I met the same problem when i call AssetBundle.Load() on Android device,if you called some functions like this?
