zenprofile
zenprofiler helps answer WHAT is being called the most. spy_on helps
answer WHERE those calls are being made. ZenProfiler provides a faster
version of the standard library ruby profiler. It is otherwise pretty
much the same as before. spy_on provides a clean way to redefine a
bottleneck method so you can account for and aggregate all the calls
to it.
% ruby -Ilib bin/zenprofile misc/factorial.rb 50000

Once you know that Integer#downto takes 50% of the entire run, you
can use spy_on to find it. (See misc/factorial.rb for the actual code):
% SPY=1 ruby -Ilib misc/factorial.rb 50000
Spying on Integer#downto
Integer.downto
50000: total
50000: ./misc/factorial.rb:6:in `factorial' via
