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 =

current clock, the page will be recompiled.  That causes an extra several=

doesn't.

I don't understand the question.  Tomcat is compiled and run under the JV=
M. =20
OpenJIT will help out the JVM by converting and executing parts of the Ja=
va=20
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.
