Ordering based on a “closest is best” analysis of the profiling call graph.
Calls that call each other frequently are placed close together.

I'm having trouble with gprof on Mac OSX and I wonder how functions that call
each other frequently can be tracked with DTrace.
Any suggestions?
There are also other orderings, e.g.
- Routines sorted by the number of calls made to each routine, largest numbers
first.
- Routines sorted by the order in which they are called.
- Routines sorted by the amount of CPU time spent, largest times first.
but these are easy to take care of with DTrace.
Thanks in advance, Joel
