response caching is not working

[sunshinecotejo]

I tried it with my API. I applied the response caching policy. I hit the API many times but the subsequent request has greater response time compared to the first one. Which is not the expected behavior.

/testAPI -- | -- | -- | -- | -- |paramKey| Response Timeout ||1st Hit | 2nd Hit | 3rd Hit | 4th Hit paramValue | 11236 ms | 8844 ms | 9099 ms | 9877 ms
