Spring boot slow starttup

This is a strange problem.

We are using spring boot web app with embedded tomcat.

On my local mac, the application launch is fast .. a few seconds. On a google machine with Centos 7 it starts very slowly .. about 2 minutes.

Application is written in JAVA 8

Can anyone please help?

Are you using Tomcat? It could be the lack of entropy causing it to block. See Spring Boot Actuator Application Won't Run on Ubuntu VPS for more details.

and @leozin :

Try to install haveged

:sudo apt-get install haveged -y



I agree that it haveged

improves startup times.

In my case (also in Centos 7, but docker in container) I had to add some -XX: MaxMetaspaceSize and the startup time went down after about 2 minutes.
