Please help my FCP and FID is high according to page insight.

Hi I need some help to reduce these FCP and FID I just recently check my webmaster console and coverage shows something slow page and check the perfomance speed under the console and use the insight tool.
Now it shows this



Do you know how to fix this issue?
I already have wprocket but not fix the issue then recently added smush and cloud flare to cache my page it improves the google insight speed score but the first content paint and first input delay still the same.

What should I do to fix the issue?

Hi, I would not worry that much. In my country pagespeed insight in webmaster is still in beta. If you checked your site with other tools (as you said) I think everything is fine.
