zenprofile version 1.3.1 has been released!

* <http://rubyforge.org/projects/seattlerb>

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
    Total time = 3.056884
    Total time = 2.390000
    
              total     self              self    total
    % time  seconds  seconds    calls  ms/call  ms/call  name
     50.70     1.64     1.64    50000     0.03     0.05 Integer#downto
     19.63     2.27     0.63   200000     0.00     0.00 Fixnum#*
     14.19     2.73     0.46    50000     0.01     0.05 Factorial#factorial
      9.93     3.05     0.32        1   320.36  3047.10 Range#each
      5.54     3.23     0.18        2    89.40   178.79 ZenProfiler#start_hook

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 
           ./misc/factorial.rb:6:in `factorial'
