Just a quick example of parallelizing network requests to improve SoA API call times to multiple endpoints using future methods.

gistfile1.rb

require "httparty"
require "celluloid"

start_time = Time.now
results = []
100.times do
  results << HTTParty.get("http://www.reddit.com/r/ruby")
end
end_time = Time.now
puts "Procedural: #{end_time-start_time}"

start_time = Time.now
methods = []
results = []
100.times do
  methods << Celluloid::Future.new { HTTParty.get("http://www.reddit.com/r/ruby") }
end
methods.each do |meth|
  results << meth.value
end
end_time = Time.now
puts "Parallel: #{end_time-start_time}"
