Mooseのパフォーマンス測定 Class::Accessor::Fast vs Moose

http://code2.0beta.co.uk/moose/svn/Moose/trunk/benchmarks/caf_vs_moose.pl

• setterは実行回数たりねーと怒られた.
• getterは大差なし
• インスタンス生成は、かなり差がある。最大100倍くらい遅い
• Destructionもかなり差がある

現状だとインスタンス作る場合には、mata->make_immutableしておいたほうがいいってこと。CGIで使うには無理がありそうだけど、そうじゃなきゃいけそうだなぁと。

DIコンテナでScopeをSingletonにしといて、startupタイミングでインスタンス作っとけば、実用上は問題ないかな。

hasとかで委譲したときに、どうなるかとかは測っておいたほうがいいかも。
