 Hi, again :)

 I'm developing wordpress websites but only using the rest api, as Headless
 CMS.

 I've blocked the frontend, and created custom endpoints to be consumed by
 a React application.

 So, more than a year pass and I'm consumed by an issue on my websites, the
 rest api it's little slow like 300ms-1000ms of time response this is a
 lot.

 As I know, I can cache the responses using transient api, I've tried that,
 but without success.

 What is the best solution to avoid database access?

 1. Should I create a wp-content/object-cache.php and cache the responses
 of endpoint?

 2.Advanced-cache.php can help me to improve the response time of rest api?

 3. do we have a method/hook/filter to check if cache exist before
 WordPress load everything /plugins/themes etc...? For example on
 https://developer.wordpress.org/reference/hooks/request/ and this hook,
 returns the response from cache without having to load every file from
 WordPress.

 I tried some cache plugins, but doesn't improve the speed?


 Any example to do this correctly, to improve the rest api time and
 database overload.


 Thanks
