Rubyforge Project:

== About

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, even if you just use Ruby’s builtin
profiler.

Action Profiler can use three profilers, Ruby’s builtin profiler class,
Shugo M.‘s Prof or Ryan D.’ ZenProfile.

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

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

=== Running Action Profiler

Typically, action_profiler will be run from the root of your Rails
application:

$ action_profiler GamesController#index
Warmup…
Profiling…
[ profile output ]
$

If you need to run action_profiler from some other path, the -p
command line
option can be used to specify the location of your Rails application.

action_profiler -p ~/Worx/X/CCR GamesController#index

Parameters can be specified after the controller and action:

action_profiler GamesController#index “:id => 1”

If you need to make sure a page is working correctly you can specify -
o. No
profiling will occur and the generated page will be printed out instead:

$ action_profiler -o GamesController#show “:id => 1”
[ lots of HTML output ]
$

== Gem Installation

gem install action_profiler

This implementation is HODEL-HASH-9600 compliant

Is it possible to drill down further, e.g. figure out exactly which
queries in PGconn#exec are
using the most time? Any idea what Site#allow_concurrency is?

Warmup…
Profiling…
% cumulative self self total
time seconds seconds calls ms/call ms/call name
29.63 0.08 0.08 14 5.71 5.71
Site#allow_concurrency
11.11 0.11 0.03 1 30.00 30.00 PGconn#exec
3.70 0.12 0.01 1 10.00 20.00
ActionController::Routing::RouteSet#generate

thanks
