Ruby EDN vs. JSON benchmark

benchmark.rb

require "active_support/json"
require "benchmark"
require "edn"
require "json"

n = 1_000_000
obj = { :hallo => "wie", :get => { :es => ["dir", 2] } }

json = obj.to_json
edn = obj.to_edn

Benchmark.bm(21) do |x|
  x.report("EDN:") { n.times { EDN.read(edn) } }
  x.report("ActiveSupport::JSON:") { n.times { ActiveSupport::JSON.decode(json) } }
  x.report("JSON:") { n.times { JSON.parse(json) } }
