Andre: Thanks and noted. Good article but does not help this problem.
Konstantin: Thanks for your notes. What is truly baffling is that I made
changes to catalina.properties for "jarsToSkip"
Before my recent changes, it took 10.5 minutes to get past the TLD scan (I
had a typo from before) Then I corrected things and get 2.5 minutes on the
Ubuntu server (the same changes made me go down to 1 second on Fedora)
So I know I am getting the right CATALINA_HOME (see no references to
CATALINA_BASE or CATALINE_BASE).
The only other difference is that the server is on a Virtual machine (Digital
Ocean) and my development server is real.
I will try what I can to see the variables you listed , but nothing makes
sense.
Baffled (for quite a while) but still trying to find it.

Also, take several (3) thread dumps to see what code is actually being executed.
https://wiki.apache.org/tomcat/FAQ/Troubleshooting_and_Diagnostics#Common_Troubleshooting_Scenario
Is Ubuntu installed manually from official Tomcat binaries provided by ASF?
https://wiki.apache.org/tomcat/FAQ/Linux_Unix#Q5
It may be that the configuration that you edited is not the one that
is actually being used.
Tomcat can be run with CATALINE_BASE != CATALINA_HOME, and some OS
vendors place Tomcat configuration files into a different place.
Print the values of system properties
catalina.home
catalina.base
tomcat.util.scan.StandardJarScanFilter.jarsToSkip
tomcat.util.scan.StandardJarScanFilter.jarsToScan
(e.g. by writing a simple JSP file that displays the values)
