performance - PHP 处理速度 apache 2.4 mpm-prefork mod_php 5.4 与 nginx 1.2.x PHP-FPM 5.4

Question

我这几天一直在寻找是否有人对 PHP 之间的处理速度进行了良好的、有记录的比较

• apache-mpm-prefork 2.4 和 mod_php 5.4

和

• nginx 1.2.x + PHP-FPM 5.4

我为什么要寻找:我看到的唯一测试是关于基准测试、提供整页或“Hello, World”之类的测试，但没有关于具体测试内容的适当文档。我不关心请求/秒数、硬件，但我确实需要查看测试了哪些 PHP 脚本以及具体的配置。

为什么是这两个: mod_php 被认为是处理 PHP 最快的(没有静态文件，没有请求/响应测量，只处理 PHP 本身)，但从那时起发生了很多变化，包括 Apache 版本。 Nginx 和 PHP-FPM 消耗的内存要少得多，因此这是更改架构的一个很好的理由，但如果在这种情况下它们不够快，那么更改将是无关紧要的。

我知道如果我找不到一个我必须自己做，但我不敢相信到目前为止没有人做过这样的测试:)

Answer 1

我已经在 CentOS 6.3 上使用 nginx 1.2.7、apache 2.4.3 和 php 5.4.12 完成了这个测试，所有这些都使用编译没有更改默认值。

./configure
make && make install

除了我启用了 php-fpm 的 php

./configure --enable-fpm

除下文所述外，所有服务器均具有 100% 默认配置。所有测试都是在测试服务器上完成的，测试之间没有负载并重新启动。该服务器配备 Intel(R) Xeon(R) CPU E3-1230、1GB RAM 和 RAID 1 中的 2 x 60GB SSD。使用 ab -n 50000 -c 500 http://127.0.0.1/运行测试测试.php

测试 PHP 脚本:

<?php

$testing = 0;

for ($i = 0; $i < 1000; $i++) {

    $testing++;

}

echo $testing;

我还必须在 nginx.conf 中启用 php，因为它默认情况下未启用。

location ~ \.php$ {
    fastcgi_pass   127.0.0.1:9000;
    fastcgi_index  index.php;
    fastcgi_param  SCRIPT_FILENAME  /var/www/html$fastcgi_script_name;
    include        fastcgi_params;
}

Nginx - 通过套接字的 PHP-FPM(配置更改为 fastcgi_pass)

我非常乐意进一步调整 apache，但 apache 似乎跟不上。明显的赢家是通过套接字使用 php-fpm 的 nginx。
