Successfully reproduced this here. That's very informative actually. It takes us here: https://github.com/spring-projects/spring-boot/blob/2.2.x/spring-boot-project/spring-boot-autoconfigure/src/main/java/org/springframework/boot/autoconfigure/web/embedded/EmbeddedWebServerFactoryCustomizerAutoConfiguration.java
As we're discussing Tomcat, this leads here: https://github.com/spring-projects/spring-boot/blob/master/spring-boot-project/spring-boot-autoconfigure/src/main/java/org/springframework/boot/autoconfigure/web/embedded/TomcatWebServerFactoryCustomizer.java This result strongly suggests that either the configuration specified by this class or the very existence of the Bean tomcatWebServerFactoryCustomizer (and thus some other part of the code) is the cause of this slowdown. I'll take a look at this hopefully in the near future; if anyone knows anything about this part of Spring please chime in.
