(続) apacheとnginxのベンチーマーク

apacheとnginxでベンチマーク
このエントリの続きとして、
apacheとnginxのベンチマークをさくらVPSでもやってみた。（静的ファイルのみ)

• 環境
  • さくらVPS -> 512MBのプラン(月額980円のやつ)
  • OS -> Debian lenny
  • nginxのphp -> spawn-fcgi

自宅からサーバにたいしてabしても結果が変わらなかったので、自宅マシンがしょぼい、もしくはサーバの上流でNWしぼられてるんだと解釈して、サーバにログインして、localhostにむけてabした結果

• 静的ファイル
  • apache

nginxがnon-blockingだからか、apacheと比べると数字がいい
failed requestが多いのが気になる

• 感想
  • 静的ファイルを捌く能力だとapacheよりもnginxが良さそう。
  • サーバの回線が細いとWebサーバの能力使い切る前にNWが、、
  • 簡単なphpを動かすくらいだとapacheと性能変わらない
    • fast-cgiのプロセス数とかもいろいろチューニングは必要そう
  • 遅いphpを使用した場合の性能劣化がapacheよりも少ないので、ブロッキングする処理をするphpとかをたくさんhostするには良さそう
    • ただ、failed requestが多いのが気になる
