Are you using 3.0-compatible webapps? If so, try setting
metadata-complete="true" in your <web-app> element: this will stop
Tomcat from scanning the JAR files for other things (not just TLDs)
and may improve startup time.

If you want to know what Tomcat is doing during those 75-seconds, take
some thread dumps and read them.
