You can use torqueProfTool in combination with gprof2dot and graphviz to visualize the profiler output like this:

The script requires python and some additional python libraries to run, details are in the README.
I have also created a wiki which includes a mini guide using the pacific profiler dump from here.
Hopefully this can help to identify performance issues and solutions. It is much easier to follow the flow of the engine in a visual format than the standard profiler output.
