SELinux can add some load between 2-20% depending on which performance
test you run."
I thoht SELinux's overhead was only for the transitions and file access
thereby being a small amount of this total time (est. at 7% untuned.)
The web app would be using Oracle's security with a MyWebAppUsername.

I don't see where it would be any greater than 7% of the volume of
transitions and file accesses (which would be different web files. And
that would be an Apache overhead whether a DBMS was being used or not.
