I have Spring Boot application 2.5.7 where I set up a micrometer to scrape metrics runtimeOnly("io.micrometer:micrometer-registry-prometheus")

When I make a request locally http://localhost:8081/actuator/prometheus There are no performance problems with my application

But when I make a request to the actuator on the server with a high load https://myserver:8081/actuator/prometheus it returns a lot more data in response and it also slows down all request that is currently running on my server. The problem appears even after one request to /actuator/prometheus

Is there any way to optimize the micrometer work(while returning the same ammount of metrics), so it will not slow down my application?

Without sufficient data it is hard to give a recommendation. If the slowness is due to insufficient memory/garbage collection, try increasing the memory of your application.

Reviewing the metrics being returned may also give you some ideas, for example if you have a high thread count, I think there is a pause when Micrometer iterates over the thread statuses. You could look into disabling that metric.
