A new profiler for Ruby will be described in the upcoming "Ruby
Developer's Guide". It is called RbProf and features:

  * Faster profiling  (10-20% overhead instead of profile.rb's 100-2000%!)
  * Focused profiling (Only *your* methods or specified methods)
  * Line profiling    (If you really need it; still costly but you can
                       turn it on and off per method-basis)
  * Saving profile data for manipulation and diffs
  * Call graph with stats and color-coded "hotspots" can be printed
      as PS, SVG, PNG etc files (if you have graphviz/dot)
  * Part of (and example in) AspectR distribution

It's finished but needs some polishing before posting to RAA. Probably a
week or two away but well in time for the december publication of the
book.
