   Hi, sorry, dont have capacity for that right now. Pasting here code which should be adopted for fast-ruby project:

   require 'benchmark/ips'
   require 'ostruct'
   
   
   # Enable and start GC before each job run. Disable GC afterwards.
   #
   # Inspired by https://www.omniref.com/ruby/2.2.1/symbols/Benchmark/bm?#annotation=4095926&line=182
   class GCSuite
     def warming(*)
       run_gc
     end
   
     def running(*)
       run_gc
     end
   
     def warmup_stats(*)
     end
   
     def add_report(*)
     end
   
     private
   
     def run_gc
       GC.enable
       GC.start
       GC.disable
     end
   end
   
   suite = GCSuite.new
   
   
   data = { x: 100, y: 200 }
   
   
   PointStruct = Struct.new(:x, :y)
   
   class FakedPointStruct
     attr_accessor :x, :y
     def initialize(x, y)
       @x = x
       @y = y
     end
   end
   
   class PointClass
     attr_accessor :x, :y
     def initialize(args)
       @x = args.fetch(:x) # NOTE: Hash#fetch -> performance impact
       @y = args.fetch(:y)
     end
   end
