Gazelle vs Meinheld

環境:

  • c3.8xlarge (32core)
  • Amazon Linux
  • Perl は yum install perl-devel したもの
  • Python は pyenv を利用して 2.7.9 をビルド
  • nginx は OpenResty (echo のため)

ボトルネックが変化してもなるべくベンチマークのオプションを変えずにCPUを使うため、 wrk, nginx, Webアプリそれぞれ16プロセス(orスレッド) を利用する。 ただし、 meinheld, minefield については、 16 プロセスだと thundering herd 問題を起こしているらしく性能が激しく劣化するので、 worker=8 にする。
