CPU spike when /refresh endpoint is hit for config refresh in the service

[rajanigk]

Describe the bug

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 acuator 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.
