fiddlesticks

Simple class to measure optimization or to find bottlenecks in your codebase.

As for now: Works on Mac. Not yet tested in Linux distributions. Not yet implemented support for Windows.

Install

gem install fiddlesticks

Gem File

gem 'fiddlesticks', '~> 0.2.0'

Use

optimize = Fiddlesticks::Core.new

optimize.measure do
  100000.times do
    "SOME STRING".downcase
  end
 end

The measure method will accept a block and print a table with usefull information that may help when optimizing your code.

+--------------+---------+-----------+--------------+-------------+--------------+
| Ruby Version | GC      | GC Sweeps | Total Memory | Memory Used | Time         |
+--------------+---------+-----------+--------------+-------------+--------------+
| 2.4.0        | enabled |        32 | 16.00 GB     | 1936.08 MB  | 1.37 Seconds |
+--------------+---------+-----------+--------------+-------------+--------------+

If you want to print out memory in different formats user configure method. It accepts a Hash with the keys:

1. total_memory: [Symbol] format: ':kb', ':mb', ':gb', standard ':gb'
2. used_memory: [Symbol] format: ':kb', ':mb', ':gb', standard ':mb'
3. gc_enabled: [Boolean] format: 'true, 'false', standard 'true'

optimize = Fiddlesticks::Core.new

optimize.configure({total_memory: :mb, used_memory: :kb, gc_enabled: false })

optimize.measure do
 #run a block of code
end

Will support Mac, Linux and Windows once the project is completed.
