気になる発言を見かけたので検証
Apache2.4以降はmod_proxy_fcgiがついてくるのでphp-fpmとの組み合わせでok。そのほうがメモリ効率も良いです。 / “nginx と php-fpm の仕組みをちゃんと理解しながら PHP の実行環境を…” https://t.co/vS8O5bZUY2

昔 nginx+php-fpm5.6 と apache2.2+mod_php5.6 でベンチマークテスト行った時に apache2.2+mod_php5.6 の方がスコア良かったので...
※何か計測方法間違ってた可能性も...
結論だけ教えて欲しい人向け
「Failed requests」少ないしFPMの方が優秀っぽい？
前提
- PHP と Apache はソースからコンパイル
- Fibonacci.php はChromeからアクセス
- ab は LISTEN IP に対して
- 一回ごとにゲストOSリブート
