Hikari startup taking time

The server bootup is very slow. I found that booting a single app in tomcat takes around 45-55 seconds as compared to 35 seconds in Jetty. One of the diffs I found is following Hikari startup takes 15 secs in tomcat setup while 5-6 secs in jetty or spring boot.

Any ideas how can I improve this?
