俺のLaravelがこんなに遅いわけがない

Last updated at Posted at 2020-04-21

Laravel

環境(ベース)

  • PHP 7.4.5
  • Laravel 7.5.1

Docker for Macでnginxとphp-fpmコンテナをunixソケットで繋いだ環境で試してます。

環境の差異

  1. OPcache なし
  2. OPcache あり、プリロードなし
  3. OPcache あり、プリロードあり

比較方法

  • Laravelのwelcome画面をabコマンドの結果で比較します。

Requests per second(1秒間に捌けるリクエスト数)、Time per request(1リクエストあたりの処理時間)に着目します。

以前こんな記事も書いてます。
Apache Bench を初めて使ってみた

OPcacheなし

php.ini(設定例)
[opcache]
opcache.enable = 0

54.25 から 301.41 へおよそ5.55倍の高速化されました！！
圧倒的すぎる速さ！！キャッシュ効果恐るべし!!

OPcacheあり、プリロードあり

php.ini(設定例)
[opcache]
opcache.enable = 1
opcache.memory_consumption = 128
opcache.interned_strings_buffer = 8
opcache.max_accelerated_files = 4000
opcache.validate_timestamps = 0
opcache.huge_code_pages = 0
opcache.preload = /var/www/preload.php
opcache.preload_user = www-data

このpreload.phpを参考にしてます。ignoreにいくつか追加してます。
ただお試し的に使ってるので、また内容まとまったら別記事にしたいと思います。

もう俺のLaravelが遅いなんて言わせない...！！

まとめ

# OPcacheなし

Time per request:       18.432 [ms] (mean, across all concurrent requests)

# OPcacheあり、プリロードなし
Requests per second:    301.41 [#/sec] (mean)
Time per request:       3.318 [ms] (mean, across all concurrent requests)

# OPcacheあり、プリロードあり
Requests per second:    347.40 [#/sec] (mean)
Time per request:       2.878 [ms] (mean, across all concurrent requests)

何も設定してない 54.25 の状態から 347.40 へおよそ6.4倍と劇的な高速化を遂げました！！！
PHPのポテンシャル半端ないですね！！！

プリロード自体は初めてなので諸々問題出てくるかもしれませんが、何か問題あったらまた記事にしていきたいと思います😃
