WordPressの高速化・PHPアクセラレータ「APC」

WordPressを2.5倍速くするPHPアクセラレータ「APC」

興味深い記事がありましたので、今回はこの「APC」というものを試してみます。

しかし現在使用しているマザーボードのCPUはC60なので、あまり期待はできそうにないかもしれません。

なるほど…現状はこれくらいだったんですね。ではAPCをインストール。

# yum -y install php-devel php-pear gcc

# pecl install apc

# vi /etc/php.d/apc.ini
extension = apc.so
apc.shm_size = 128M
apc.enable_cli = 1
;apc.filters = filename

インストールや設定等はサイトの手順通りに行えば問題なく進みます。

若干速くはなりましたが、やっぱりC60ではこんなものですね。処理速度より低消費電力重視で選びましたから… (^^;)
