Hi,
Now OpenNMS has switched to a git repo I've been making the effort to
clean the tree to a reasonable state so I can push some of the stuff
in our tree upstream.
The following two patches add command line switches to the opennms
binary to enable various profiling approaches. I've used TIJMP a bit
for looking for memory load but I must admit the OProfile support has
been a lot more useful, especially for the locating CPU bound
hotspots.
The patches are attached, the oprofile one applies after the tijmp
one.

Enable OProfile profiling support
This patch to the opennms start up script allow a command line flag to
be passed that will load the OProfile JVMTI module. This module will
allow OProfile to show more detail as to where hot-spots are than just
the big chunk of anonymous memory allocated for Java's JIT code.
