APC PHP をテストする

PHP のコンパイルと APC キャッシュの効果をテストします。
ab test を使用するコマンドは次のとおりです: /ab -n 1000 -c 5 http://localhost/abtest.php
APC をオンにする:

APC をオンにしないでください:

APC が有効になっています:
 

使用 テスト用のファイル abtest.php には、データベース接続を使用しない、クラスの導入とインスタンス化が含まれています。
テスト結果:
APC をオンにしてもオフにしても、CPU 占有率は 100% であり、処理能力は同じです。完了時間は以下の通りです:
テストに要した時間: 11.464 秒
テストに要した時間: 29.521 秒
テストに要した時間: 10.361 秒
テストに要した時間: 28.444 秒
当たり前ですが、ほぼ 3 倍です。
