Hi Ramli,
Thanks for getting in touch with us.
It is likely not caused by Rank Math since Rank Math does not add anything in the frontend.
If you are checking while logged in, Rank Math adds some elements to the admin bar but the time difference shouldn’t be that much.
You can use the query monitor to see what’s causing the lag: https://wordpress.org/plugins/query-monitor/
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
