refresh endpoint causes CPU spikes

[rajanigk]

spring-boot version: 3.1.4
spring-cloud version : 2022.0.3 ( same is observed since spring cloud HOXTON release)

Sample
we are using spring-cloud-config-server with s3 backend. When we do config refresh using the actuator endpoint refresh, in the spring boot application using spring-cloud-config-client library, we see huge CPU spike. it is requiring atleast 7-8 times the normal CPU needed by the application. Is this behaviour expected? I observed this CPU spike even if we have not used @RefreshScope in any class to absorb the dynamic config change. Filed the github issue in spring cloud as well. CPU spike when /refresh endpoint is hit for config refresh in the service #2325 , but no update there, then filed the issue at spring-guides/gs-centralized-configuration#28, this issue was closed and they suggested that i openn the issue in spring-boot.

Had you made it clear that you had already opened a Spring Cloud issue I doubt that @Buzzardo would have suggested opening another issue. spring-cloud/spring-cloud-config#2325 is the right place for the investigation to begin.

To increase the chances of the Spring Cloud team spending some time diagnosing your problem and helping you, I strongly recommend spending some time providing them with a minimal sample that reproduces the problem.

No, I would never ask for someone to create a duplicate issue.
