MySQL と PostgreSQL の速度比較 [RDBMS]
http://www.thinkit.co.jp/free/article/0603/10/5/
めちゃくちゃ乱暴に言うと
・MySQL(ISAM) の方が PostgreSQL より 2.5 倍くらい早い
・MySQL(InnoDB)と PostgreSQL なら MySQL のが速いけど、ほとんど同じ
って感じだな。
ベンチマークなんて取ったことないし、そんなギリギリの性能について必要になったことないけど、なんとなく思ってたのと一致する。
ベンチマークを取る直前に Vaccum しているあたりで、 PostgreSQL の性能を割り引いてみてあげないといけないと思うが、あとは、2.5 倍の速度差を、差があると見るかどうかだな。
一ついえることは、アプリケーションの作りでそれ以上の差は付くってこと。
必要な回数の 100倍くらいクエリーを発行していて、せっかく MySQL を使っていても台無しにしていることも多々あると思う。
むしろ、RDBMS の性能を落とさないようにうまくプログラミングできてることのほうが少ない。
だから、実戦ではどっち使っても大差ないような気がする。
むしろ、ベンチマークを取った２つのバージョンで言えば MySQL の方は日本語の取り扱いに問題がありそうで使いたくないなぁ・・・とか、性能以外のところで考慮することがあるように思う。
