MemoryProfilerでメモリについて調べてみる

メモリ Ruby

こんにちはサーバーサイドエンジニアの乙です。

コードを書いているときに「このオブジェクトはどれだけのメモリを使用しているんだろう?」と考えるとことはありませんか?まずはインストール不要で使える組み込みライブラリのObjectSpaceを使ってみましょう。

docs.ruby-lang.org

ObjectSpace#memsize_ofを使ってみる

require 'objspace'

arr = Array.new
ObjectSpace.memsize_of(arr)
=> 40

40が返されました。色々試してみて小さなオブジェクトだと40バイトと返されることが多いようです。ChatGPTに質問してみました。

はい、ObjectSpace.memsize_of が返す値はバイト単位で、Rubyオブジェクトのヘッダーサイズを含んだオブジェクトのメモリサイズを表します。このヘッダーサイズは64bitの環境では40バイトで、固定のため一部の小さいオブジェクト（例えば一部の数値、シンボル、特定の小さいクラスのインスタンスなど）では40と表示されることがあります。

また#memsize_ofを使う上で以下のことを覚えておいたほうが良さそうです。

ObjectSpace.memsize_of が返す値はオブジェクトのヘッダーサイズを含みますが、そのオブジェクトが参照している他のオブジェクトのメモリサイズは含まれません。また、一部の種類のオブジェクト（例えば文字列や配列など）は内部的に追加のメモリを確保する場合があり、その追加のメモリも ObjectSpace.memsize_of の返す値に含まれます。 なお、オブジェクトによってはメモリ使用量がオブジェクトの内容に依存するため、40バイト以上の値を返すこともあります。たとえば、文字列オブジェクトの場合、文字列の長さによってメモリ使用量が増加します。

MemoryProfilerのインストール

次はMemoryProfiler を使ってみます。今回は適当なUserをたくさん作りたかったのでfakerも一緒にインストールします。

github.com

gem install mamory_profiler faker

1000個のUserクラスのインスタンスを作成するmain.rbを作成し、コマンドラインから出力させてみます。

# main.rb
require 'faker'
  
class User  
  def initialize(id:, name:, email:)
    @id = id
    @name = name
    @email = email
  end
end 
  
users = []  
  
1_000.times do |i|
  users << User.new(
    id: i,  
    name: Faker::Name.name,
    email: Faker::Internet.email,
  ) 
end

ruby-memory-profiler main.rb -o output.txt --retained-strings=5 --allocated-strings=5

すると output.txt に次のように出力されるはずです。(ruby-memory-profiler -hでオプションを教えてもらえます)

Total allocated: 145658782 bytes (1844451 objects)
Total retained:  15949395 bytes (280320 objects)
