ab(Apache Bench)で負荷をかけてみた - 公開懺悔はてな日記

memcacheが動いているし高速になったんだろうとApache Benchで負荷をかけてみた。

abを使って

ab -n 100 -c 10 https://www.barasu.org/

結果は・・・・

apr_poll: The timeout specified has expired (70007)

それならばと-n -cの数値を低くしてやってみた。それでも同じエラー(x_x)

静的コンテンツだったらいけるなぁ

動的コンテンツ(WordPress)だと

うぐぐぐぐぅ～

Micro Instanceの限界?

memcacheが効いているかどうかの確認したかったのにぃ～負荷分散装置配下にWebサーバを複数台用意するべき?

スケールアウトを考えた方がいいのかな? スケールアップを考えた方がいいのかな?

悩み中。

構成から見直す必要あるのかなぁ。

現在の構成は WordPress×1,memcached×1,RDS+CloudFront
