Doesn't the "synchronized" in the above mean that you're essentially
single-threading Tomcat? So you have all this infrastructure... and that sync
may well be the bottleneck.
You could detect this by taking a thread dump in the middle of the day, and
seeing whether a significant number of threads were waiting on either of your
sync objects. If there are a significant number, consider re-engineering this
critical piece of your application to be multi-threaded :-).
