BenchmarkTime

Benchmark the execution time of an arbitrary block of code. Specify concurrent <<<<<<< HEAD threads and number of execution loops for more robust sampling.

BenchmarkTime is especially built to benchmark things like external services, rather than ruby code itself. It can do something like a small scale load test of external dependencies and give you a benchmark with concurrency.

Installation

Add this line to your application's Gemfile:

gem 'benchmark_time'

And then execute:

$ bundle

Or install it yourself as:

$ gem install benchmark_time

Usage

# Benchmarking rabbitmq with bunny:

require 'benchmark_time'
require 'bunny'

# Benchmark connecting and filing an item into rabbitmq with bunny
benchmark_time(num_threads: 10, num_loops: 5) do
  conn = Bunny.new
  conn.start
  ch  = conn.create_channel
  q   = ch.queue("test1")
  q.publish('hello bunny')
  conn.stop
end

# Options for benchmark_time:

  :work_warmup_proc A proc to call for each thread. this can pre-warm connections, 
  or perform oother non-timed work.

  :num_threads          Number of concurrent threads to execute the work

  :num_loops            Number of times to call the block in each execution thread.

  :loop_delay           Delay after each loop. (defaults to 0)

  :show_values          If printing output show actual variable values (good at small scale)

  :print_results        If true, puts the result to sdtout at the end.

  :garbage_collection   If false (default) garbage colleciton will be off during the loop to benchmark.
