When I first tried gprof few months back, I tried with simple axis
server. I have to figure out how to deal with Apache module, and it is
most likely that we may have to recompile.

This tool looks great. (on mine it is callgrind, or kcachegrind). We do
not need to recompile.
However, it gives an error with httpd, even with -X:
DWARF2 CFI reader: unhandled CFI instruction 0:22

So I ran with simple axis server. The result file for two calls is here: 
http://tools.wso2.org/~samisa/callgrind.out.20556. You can use 
callgrind_annotate or kcachegrind to view info in desired manner.
