I am passionate about Ruby, but its execution time compared to other languages is extremely high, especially when we want to use more complex algorithms. In general, data structures in interpreted languages become incredibly slow compared to compiled languages. Some algorithms such as ´n-body´ and ´fannkuch-redux´ can be up to 30 times slower in Ruby than Go. This is one of the reasons I was interested in embedding Go code in a Ruby environment.

For those who do not know how shared libraries operate, they work in a similar way as DLLs in Windows. However, they have a native code with a direct interface to the C compiler.

Note Windows uses the DLL system, and in this case, this does not necessarily have to be in native code.

One example is DLLs written in C#, which runs on a virtual machine. Because I do not use windows, I ended up not testing if it is poss

	module RailsAppName
	class Application < Rails::Application
	# .... your settings

	require "#{Rails.root}/lib/cloud_flare_middleware"
	config.middleware.insert_before(0, Rack::CloudFlareMiddleware)

	# ... your settings
	end
	end

	# More robust version to update new or existing counter cache columns in your Rails app.
	# See: https://gist.github.com/svyatov/4225663
	desc 'Update all cache counters'
	task :update_cache_counters => :environment do
	models_to_update = {}

	# or: Rails.application.eager_load!
	# Dir loads less, so it's faster
	Dir.glob(Rails.root.join('app/models/*/')).each { \|model\| require model if File.file?(model) }
