class Benchmark::IPS::Report

Perform operations like add new entry, run comparison between entries.
Report contains benchmarking entries.

def add_entry label, microseconds, iters, ips, ips_sd, measurement_cycle

Returns:
  • (Report::Entry) - Last added entry.

Parameters:
  • measurement_cycle (Integer) -- Number of cycles.
  • ips_sd (Float) -- Standard deviation of iterations per second.
  • ips (Float) -- Average Iterations per second.
  • iters (Integer) -- Iterations.
  • microseconds (Integer) -- Measured time in microsecond.
  • label (String) -- Entry label. 
def add_entry label, microseconds, iters, ips, ips_sd, measurement_cycle
  entry = Entry.new(label, microseconds, iters, ips, ips_sd, measurement_cycle)
  @entries.delete_if { |e| e.label == label }
  @entries << entry
  entry
end

def data

Returns:
  • (Array] Array of hashes with :label, :ips, :stddev) - Array] Array of hashes with :label, :ips, :stddev 
def data
  @data ||= @entries.collect do |entry|
    {
      :name => entry.label,
      :ips =>  entry.ips,
      :stddev => entry.ips_sd
    }
  end
end

def generate_json(path)

Parameters:
  • path (String) -- path to generate json. 
def generate_json(path)
  File.open path, "w" do |f|
    require "json"
    f.write JSON.pretty_generate(data)
  end
end

def initialize

Instantiate the Report. 
def initialize
  @entries = []
  @data = nil
end

def run_comparison

Run comparison of entries. 
def run_comparison
  Benchmark.compare(*@entries)
end
