a huge cost of animator

Hi, i found my project have a very low fps. I have tried to profile it, and get this chart.

Is there any idea about the “Loading.ReadObject” ? What cost this ?

Should I perloading all animator objects ? And how to perloading it ?

Thank you .

I’m having similar issues, animator is taking around 20-25% of the cpu on my phone, I’ve spent lot of time trying to optimize without luck… looks like mecanim is not yet suitable for mobiles at least android :confused:
