BenchmarkGC

A lightweight gem for benchmarking garbage collect stats relevant to memory optimization.

Add this line to your application's Gemfile:

gem 'benchmark_g_c'

And then execute:

$ bundle

Or install it yourself as:

$ gem install benchmark_g_c

class Thing
  include BenchmarkGC

  # A method you want to benchmark
  def method_name
    do_some_stuff
  end

  # Add this method in order to benchmark (name doesn't matter)
  def check
    bcheck { method_name }
  end
end

In a console:

Thing.new.check

• name: (string) Print the name of the benchmarked code
• times: (integer) Number of times to run the benchmarked code in succession
• logger: (boolean) ActiveRecord::Base.logger should log

class Thing
...
  def method_name
    bcheck { do_some_stuff }
  end
end

Now you can run any code that uses method_name, and method_name will get benchmarked each time it is run.
