Wso2 EI 7.1.0 response processing slow - wso2

Question

I am using Wso2 EI 7.1.0 for one of my ESB use case. I implemented flow like API mediator-->Iterate mediator-->Send mediator--->Aggregate--->Payload Factory--->Respond, here I am facing more time taking at Payload Factory while responding, I am using default configurations and I tested this at Linux 16 Core + 32 GB RAM server. I am adding template XML, please assist.
