In my experience, TPTP is something to run away from as fast as possible. It's a horribly overengineered mess, almost impossible to get to work, badly documented, and slow as molasses.
I'm not aware of any good and free profiling plugins for eclipse. But then, does it really have to be an eclipse plugin? VisualVM comes with the JDK since Java 6u7, is fast and easy to use. It may not be the most feature-rich of profilers, but has been sufficient for me.
