it depends what you mean if you talk about Pharo code then those tools should be enough , unless it freezes Pharo (a 100% consumption does not necessarily imply a freeze)
if you talk about the Pharo VM itself then you will need to use one of the countless profilers that exist for C/C++ . Some OSes come included with them. MacOS which what I am using can sample a running process and tell you exactly which function/method consumes how much CPU. Obviously more specialised tools can be even more of an assistance like Valgrind http://valgrind.org/ But then it will require knowledge of the Pharo VM internals. if it freezes pharo and you know its pharo code then its a matter of taking a look at changes file and testing on a new image one change at the time until you identify the code that causes the slow down. At least that is what I have done one time I really messed up Morphic draw loop and froze my image.
