= Action Profiler

* http://seattlerb.rubyforge.org/action_profiler
* {action_profiler Bug Tracker}[http://rubyforge.org/tracker/?func=add&group_id=1513&atid=5921]

== DESCRIPTION:

action_profiler allows you to profile a single Rails action to determine what
to optimize.  You can use the Production Log Analyzer and action_grep to
determine which actions you should profile and what arguments to use.

Information on the Production Log Analyzer can be found at:

http://rails-analyzer.rubyforge.org/pl_analyze

=== Profilers

Action Profiler REQUIRES Ruby 1.8.3 or newer, even if you just use
Ruby's builtin profiler.

Action Profiler can use three profilers, ZenProfile, Ruby's builtin
profiler class or Shugo Maeda's Prof.

Shugo Maeda's Prof: http://raa.ruby-lang.org/project/ruby-prof

ZenProfile: http://rubyforge.org/frs/?group_id=712&release_id=2476

=== Running Action Profiler

See ActionProfiler
