It's very difficult to tell what might be the cause of these timing
differences without knowing what code is running.

How are you running the code inside Tomcat? Are you using modjy, the
WSGI gateway? Or are you running a servlet written in jython?

For the curve labelled "jython" in your graph, what WSGI server are
you using for that? Did you use the same WSGI server for your cpython
timings?
