這邊預計要測試以下組合：
php -S)硬體配備：
備註：
使用 Apache prefork-mpm，設定如下：
<IfModule mpm_prefork_module>
StartServers 100
MinSpareServers 100
MaxSpareServers 150
MaxRequestWorkers 250
MaxConnectionsPerChild 0
</IfModule>
目標頁面為 info.php：
<?php
phpinfo();
使用 ab (Apache Benchmark) 進行測試。
測試包含以下項目：
每個連線會連續發出 100 個 request 並持續到所有連線收到 response。
一次一個連線，並連續送出 1000 個 request：
ab -r -c 1 -n 1000 http://192.168.1.2/info.php
一次 10 個連線，每個連線均送出 1000 個 request：
ab -r -c 10 -n 10000 http://192.168.1.2/info.php

使用 unix socket 來串接 apache 與 php-fpm，效果與使用 http proxy 還要好。
藉由上面的測試果可以注意到 Requests per second 平均增加了 40 個左右 (約 8 %)
使用 nginx 將 requestw proxy 給 php-fpm 處理。
nginx 設定：
location ~ \.php* {
root /home/www/data;
include fastcgi_params;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
php-fpm 的設定維持預設值：
listen = 127.0.0.1:9000
pm = dynamic
pm.max_children = 50
pm.start_servers = 5
pm.min_spare_servers = 5
pm.max_spare_servers = 35

注意：還是有約 40% 的 non-2xx error
從前一項測試可以看出 non-2xx error 和 Nginx worker 沒關係。
這次把 php-fpm 的 process 數量限制放寬，看看狀況有沒有比較好：
pm.max_children = 100

注意：non-2xx 的 error 下降到約 16%，所以可能和 max_children 設定有關。
這次故意把 max_child 調低，看看是否會讓錯誤爆增：

備註：
non-2xx error，表示應該經超過 PHP built-in server 可以負荷的 concurrency 了做完壓力測試以後有幾個可以討論、注意的地方：
concurrent = 1 的結果差異都很大，不建議拿來當作參考php-fpm 即使到達最大的 process 數量，也還是可以處理大量的同時連線，且速度不會下降php-fpm 使用 unix socket 模式與 HTTP server 串接，速度有比較快一些 (5 ~ 8%)php-fpm 的 socket 模式在相同的 concurrent 下，似乎比較早遇到效能瓶頸 (會出現 non-2xx error，原因不明)。若將 php-fpm 的 max_child 增加可以解決問題。php -S 是目前效能最好的，但 log 的資訊量最少 (沒有 user-agent、runtime、response size 等)Failed requests 是 ab 已知的 bug，可以忽略：fake failed requests (length)
