Performance issues - How to pass Core Web Vitals

We'd like to move to ReadMe but have concerns about performance of the ReadMe platform and failing Core Web Vitals. This is important given we need to be able to drive organic search traffic to our documentation and will be more critical in March 2024 when Google replaces FID with Interaction to Next Paint (INP).

Is this a known issue and are there any recommendations to be able to get a ReadMe powered site to pass Core Web Vitals?

https://docs.readme.com fails and other sites known to use ReadMe have even poorer metrics
