I used the "recipe", including using the "start-tomcat" Run Configuration that Tomcat provides. >> Note the initial log timestamp (10:54:57) and the final one (11:00:59). >> That's 4 minutes to launch and deploy docs, examples, host-manager, >> manager, and ROOT.

I could post some full dups if you think that would be helpful.
