Profiling

Noosfero supports* newrelic_rpm, fiveruns_tuneup and rails performance testing for profiling.

* See code at https://github.com/coletivoEITA/noosfero-ecosol/tree/profiling

Configuration

Edit config/database.yml and config/solr.yml to create the profiling environment. Replace the development definition to:

    development: &DEVELOPMENT

And add the profiling environment:

profiling:
  <<: *DEVELOPMENT

Setup

Install profile tools:

gem install fiveruns_tuneup
gem install newrelic_rpm

To use newrelic_rpm and fiveruns_tuneup run the webserver using the 'profiling' environment:

script/server thin -e profiling

NOTE: newrelic_rpm is incompatible with fiveruns_tuneup enabled. Disable the latter to use the former. (See config/environment.rb and config/environments/profiling.rb)

Use

fiveruns_tuneup will show up in the top of every page.

newrelic_rpm reports are accessible at '/newrelic'

To run a performance test use:

RAILS_ENV=profiling script/performance/profiler test/performance/script.rb
