超高速WordPress仮想マシンKUSANAGIの速度を比較してみる（その1）

前回の記事では、さくらのVPSでKUSANAGIの環境を構築する（ほぼ手間無し）までやったので、どれ程までに超高速なのか、どの仕様が早いのかを、条件を変えながら測ってみた。

まず、今のnakayan.jpをチェックする。　VPSのスペックはメモリ1GB、CPU2コアの年間1万円のプランだ。

ab -n 10000 -c 300 https://nakayan.jp/

上記を実行した結果がコレ。

大雑把な目安として、HTTPSで秒間260アクセスまでいけるってこと。

あくまでも参考値ね。

さて、KUSANAGIの速度検証として、下記のパラメータを変えながら試してみよう。

テーマはSimplicity2、検証時点でのバージョンの2.5.8を使用。
本サイトの約3,000件の記事をインポート、ただし画像は無し。
Siteguard LiteとSSLは、面倒だから今回の検証からは除外する。　そのうち調べたい。
NGINXとApacheの切替はKUSANAGIコマンドを使用せず、都度クリーンインストールする。
abコマンドは3回やって、Requests per secondの中央値だった結果を採用する。

そうすると、組み合わせは下記のようになる。

メモリ1GB、CPU2コア、NGINX
メモリ1GB、CPU2コア、Apache
メモリ2GB、CPU3コア、NGINX
メモリ2GB、CPU3コア、Apache

では結果。
