Description
Running a project with >10k external properties.
It seems that Spring is taking a long time with processing all property binding, and also contains a deep stack.
I'm not sure how to proceed further with this or optimize, or if this is simply that needs to be worked on from a performance point.
Flight recording attached.
Spring boot 2.3.12

Research direction
Start with SpringIterableConfigurationPropertySource and reproduce the report using more than 10k external properties on Spring Boot 2.3.12. Inspect the attached flight recording and use the reported deep stack as the first performance lead. The issue does not name a file, test, or concrete completion criterion, so the expected optimization still needs to be established.
