【php】php5.6とphp7.0をwordpressで比較してみた

はじめに

php5.6からphp7.0にしたらどれくらい速くなるのかというのを試してみただけ
環境としてはローカルPCにvagrantでcentos6.7、php5.6、mysql5.6、apache2.2.15をインストールして
最新バージョンのwordpressをいれてダミーデータを登録してapache benchでレスポンスを比較
また、apachemysqlのチューニングは一切なしで

環境の構築についてはこちらのとおり
【vagrant】開発環境をサクッと作るときの手順メモ - とりあえずphpとか
【wordpress】wordpress検証用環境を作ったので構築手順メモ - とりあえずphpとか

結果

apache benchコマンド

$ ab -n 100 -c 20 http://192.168.33.10/

php5.6

Requests per second:    1.96 [#/sec] (mean)
Time per request:       10220.889 [ms] (mean)
Time per request:       511.044 [ms] (mean, across all concurrent requests)

php7.0

Requests per second:    6.17 [#/sec] (mean)
Time per request:       3242.168 [ms] (mean)
Time per request:       162.108 [ms] (mean, across all concurrent requests)

「Requests per second」を見ると1秒間に捌けるリクエスト数が3倍になってる。。。
検証用アプリも自前で用意してもう少し色々調べた方がいいとは思うが、wordpressに70記事くらい登録した状態でもこれだけの差が出たのでかなり速くなったと思って良い気がする

以上です
