share me the website link, i wanna check the performance.

this screenshot and my lighthouse say FCP is bad on mobile.

i guess speed index can be improved with loading as well.

lighthouse checkes all performances as low level, so mobile is bad even it's same code.

do you use cache?

i suggest to use cache.

react-query is the one of cache library
