The startup, loading the JVM, each context, etc. will take some resources, 
yes.  Also, the first time you access a page with a newer timestamp than the 
current clock, the page will be recompiled.  That causes an extra several 
seconds for the first acceess.  When you start breaking pages up to include 
other pages, you need to learn what gets automatically recompiled and what 
doesn't.

I don't understand the question.  Tomcat is compiled and run under the JVM.  
OpenJIT will help out the JVM by converting and executing parts of the Java 
byte code to native code.  That's what a JIT does, to my understanding.

Nonetheless, I'm glad to hear that you've had an increase in performance.

Take care.
