約２倍ほど早くなりました。
キャッシュ系のプラグインを使用していましたが、もう不要かもしれないです。
もっと早く気づきたかった…
パッケージのインストール
apt install php7.0 apt install php5-mysql apt install libapache2-mod-php7.0 apt install php7.0-gd apt install php7.0-xml apt install php7.0-xmlrpc apt install php7.0-mbstring
php5からphp7.0への切り替え
a2dismod php5 a2enmod php7.0 /etc/init.d/apache2 restart
※php.iniは元々手を加えていた差分だけマージすれば良さそうです
