ACL performance gap between baremetal and linux. #1065

Hello, Now, we are using acl library to run cnn model on bare metal device. We test the same model on linux and bare-metal. We found it has about 5× latency.

 environment: linux + a57 vs bare metal + a53

Is there having some differences between bare metal and linux?

Hi @goldhandsome

Could you please share more details about the model you're running? Is it a well known model like mobilenet?

Can you please share the performance figures you observe?

How do you run the model on Linux? How do you run the model on bare metal? Do you use one of our graph examples? if so what command you use to execute the model?
