It would be really great, if the {Server-Timing}-Header would be supported. Either as part of the Spring Boot Devtools or as Part of MVC?
This may be implemented as Servlet Interceptor and gives Web-Debug tools like the Chrome Devtools or Firefox Developer Tools the chance to display something like persistence query times, Disk-I/O-wait and such.
Maybe some numbers are already present beacause of Spring's metrics support.

Has anyone looked at https://github.com/sercasti/spring-httpserver-timings ? I've been using it with some modification to actually aggregate metrics within a request context with some success.

Thanks for the pointers. There is an issue in the Boot backlog https://github.com/spring-projects/spring-boot/issues/8736 so I've added this to ours until it's more clear what is required where.

Since the introduction of the Observation API usage in Framework itself, we don't believe additional support in Spring Framework is required.
