SpeedupRails

SpeedUpRails is a development helper for a rails application. It collects performance data in Rails application. For longterm vizualization you can use a counterpart engine called speedup-dashboard. But you can use 3rd party vizualization as well, Grafana with InfluxDB engine is a good example.

The easiest way to install speedup-rails is by using Ruby Gems. To install put in your Gemfile:

gem 'speedup-rails'

You can configure speedup-rails trough the environment files, or yml file in Rails.root/config/speedup-rails.yml with format:

development:
  disabled_collectors:
    - bullet

In file you can disable collector like:

In development environment all you have to do is include a gem in your Gemfile. But you can wish to choose an adapter for storing a request data. Available adapters are:

• Memory - default in development
• File - default in all but development
• Redis
• Memcached (via Dalli)
• InfluxDB
• Server - send via asynchronous HTTP request

Adapter can be chosen in config file:

  Rails.application.configure do
    config.speedup.adapter = :server, {url: 'http://path/to/server', api_key: '<your_key_generated_by_server>'}
  end

There is implemented server side application as Engine, so best is to use it: https://github.com/ezrondre/perfdashboard

In developement you can see the speedup toolbar at bottom of your page. It is available for all your request ( even for redirected and ajax ones ) and shows information from all allowed collectors.

You can disable it by, or set some css styles - for now just an zindex, but there are expected more options.

  config.speedup.show_bar = false

  config.speedup.css[:zindex] = 10

Well that depends on what collectors you allow.

This is your options:

• Request - prety mandatory, without performance impact
• Queries - not as mandatory. Impact is pretty low, but if you have a lot of queries in your request, you can consider it.
• Partials - same as queries, but watching over rendered partials.
• Bullet - Using a bullet and vizualize its results.
• Profiler - Using a rubyprofiler to profile full request or

every option is in form of collector

Collectors are defined by a configuration ( in environment file or in application.rb)

Add Profiler collector:

  Rails.application.configure do
    # config.speedup.collectors << :rubyprof
    config.speedup.collectors << {rubyprof: {profile_request: true} } #collector with options
  end

default collecotors are :request, :queries, :partials ( + :bullet and :rubyprof in developement )

Everything you need to do is enable rubyprof collector ( default in developement ) and wrap profiled code in block:

  Speedup.profile do
    ...
  end

if you want to profile full request, just set

  { profile_request: true }

in rubyprof options
