初探yaf,兼对比yii、drupal的性能比试

Yaf是一个国人用C语言编写的PHP框架,号称最快的php框架,项目主页是:http://www.yafdev.com/

一、安装

yaf已经被收录进pecl,所以安装也特简单:

pecl install http://pecl.php.net/get/yaf

如果提示错误:

ERROR: `phpize' failed

需要先安装php开发版:

yum install php-devel
yum install pcre-devel

yaf安装成功后提示:

Build process completed successfully
Installing '/usr/lib64/php/modules/yaf.so'
install ok: channel://pecl.php.net/yaf-2.2.9
configuration option "php_ini" is not set to php.ini location
You should add "extension=yaf.so" to php.ini

将yaf.so加入php:

vim /etc/php.d/yaf.ini

写入以下内容:

; Enable yaf extension module
extension=yaf.so

重启php-fpm或httpd即可生效。

service php-fpm restart
service httpd restart

二、Hello, world

假设项目目录为yaf,在yaf下建立以下结构:

yaf
├── application
│   ├── controllers
│   │   └── Index.php
│   └── views
│       └── index
│           └── index.phtml
├── conf
│   └── application.ini
└── public
    └── index.php

其中,public是web的根目录,需要在web服务器配置里设置一下。 上面树状图中的四个文件需要写入内容, 入口文件:

vim yaf/public/index.php
<?php
define("APPLICATION_PATH",  dirname(dirname(__FILE__)));

$app  = new Yaf_Application(APPLICATION_PATH . "/conf/application.ini");
$app->bootstrap() //call bootstrap methods defined in Bootstrap.php
    ->run();

配置文件:

vim yaf/conf/application.ini
[product]
;支持直接写PHP中的已定义常量
application.directory=APP_PATH "/application/"

控制器:

vim yaf/application/controllers/Index.php
<?php
class IndexController extends Yaf_Controller_Abstract {
   // default action name
   public function indexAction() {  
        $this->getView()->content = "Hello World";
   }
}
?>

视图:

vim yaf/application/views/index/index.phtml
<html>
 <head>
   <title>Hello World</title>
 </head>
 <body>
   <?php echo $content; ?>
 </body>
</html>

 

三、性能测试

yaf是用c写的php扩展,号称最快的php框架,当然要ab测试一下: ab -n 10000 -c 100 网址 并发100,访问1万次,结果如下:

Document Path:          /
Document Length:        107 bytes

Concurrency Level:      100
Time taken for tests:   2.849 seconds
Complete requests:      10000
Failed requests:        0
Write errors:           0
Total transferred:      2711355 bytes
HTML transferred:       1070535 bytes
Requests per second:    3510.41 [#/sec] (mean)
Time per request:       28.487 [ms] (mean)
Time per request:       0.285 [ms] (mean, across all concurrent requests)
Transfer rate:          929.49 [Kbytes/sec] received

同一台服务器的drupal7开启页面缓存后,同样测试命令,结果如下:

Document Path:          /
Document Length:        15028 bytes

Concurrency Level:      100
Time taken for tests:   6.444 seconds
Complete requests:      10000
Failed requests:        0
Write errors:           0
Total transferred:      154790000 bytes
HTML transferred:       150280000 bytes
Requests per second:    1551.80 [#/sec] (mean)
Time per request:       64.441 [ms] (mean)
Time per request:       0.644 [ms] (mean, across all concurrent requests)
Transfer rate:          23457.39 [Kbytes/sec] received

同样条件的yii测试结果:

Document Path:          /demos/helloworld/
Document Length:        11 bytes

Concurrency Level:      100
Time taken for tests:   6.978 seconds
Complete requests:      10000
Failed requests:        0
Write errors:           0
Total transferred:      1751050 bytes
HTML transferred:       110066 bytes
Requests per second:    1433.14 [#/sec] (mean)
Time per request:       69.777 [ms] (mean)
Time per request:       0.698 [ms] (mean, across all concurrent requests)
Transfer rate:          245.07 [Kbytes/sec] received

意外发现Yii很杯具,于是试试Yii的blog演示:

ab -n 1000 -c 30 blog网址
Document Path:          /demos/blog/
Document Length:        5281 bytes

Concurrency Level:      30
Time taken for tests:   8.769 seconds
Complete requests:      1000
Failed requests:        0
Write errors:           0
Total transferred:      5640000 bytes
HTML transferred:       5281000 bytes
Requests per second:    114.04 [#/sec] (mean)
Time per request:       263.058 [ms] (mean)
Time per request:       8.769 [ms] (mean, across all concurrent requests)
Transfer rate:          628.13 [Kbytes/sec] received

悲摧!发现Yii比未开启缓存的drupal也好不了多少! 忍不住又测试一下同一台机器的drupal6,不开启缓存:

Document Path:          /
Document Length:        4966 bytes

Concurrency Level:      30
Time taken for tests:   4.681 seconds
Complete requests:      1000
Failed requests:        0
Write errors:           0
Total transferred:      5304000 bytes
HTML transferred:       4966000 bytes
Requests per second:    213.61 [#/sec] (mean)
Time per request:       140.441 [ms] (mean)
Time per request:       4.681 [ms] (mean, across all concurrent requests)
Transfer rate:          1106.45 [Kbytes/sec] received

裸奔的drupal6性能是yii的两倍! 再测试裸奔的drupal7,结果如下:

Document Path:          /
Document Length:        15028 bytes

Concurrency Level:      30
Time taken for tests:   11.545 seconds
Complete requests:      1000
Failed requests:        0
Write errors:           0
Total transferred:      15476000 bytes
HTML transferred:       15028000 bytes
Requests per second:    86.62 [#/sec] (mean)
Time per request:       346.337 [ms] (mean)
Time per request:       11.545 [ms] (mean, across all concurrent requests)
Transfer rate:          1309.13 [Kbytes/sec] received

性能测试小结(同一服务器比较,数字说话)

处理请求/秒

静态html —— 1万+

原生php  —— 5k

Yaf helloworld —— 3510.41

Yii helloworld —— 1433.14

Yii blog —— 114.04

drupal6(不缓存)—— 213.61

drupal7(不缓存)—— 86.62

drupal6(匿名缓存)—— 858.68

drupal7(匿名缓存): 1551.80

测试环境: dell服务器四核4G内存,centos6 64位版,php5.3.26 + eAccelerator

从以上数据分析可得,yaf的helloworld测试是很快的,比起原生php仅损失30%的速度。

然而,从yii helloworld和yii blog性能对比可知,单页面的测试对比成型系统(哪怕只是一个简单的blog),根本不是一回事,毫无借鉴意义。鉴于未发现构建于yaf之上的cms系统,因此只能通过yaf和yii的helloworld对比,简单推导出yaf blog的性能,应该大约是279请求/秒。

本来我是用drupal作为参考对比,但测试后意外发现,drupal6的性能居然比yii blog还好。要知道,一个裸奔的drupal,已经包含文章发布/多用户管理/权限设置/日志访问等基本功能,远比yii blog这个演示版本复杂。

但是不是可以下结论,drupal做出来的站点比yii性能更好?也未必,因为drupal架构决定了,安装模块越多性能下降越快,而且是不可控制的。也许当功能复杂到某个程度时,达到某个临界点,drupal的性能就会被yii赶上也未可知。目前只可以说,这些框架还是系统,其实都是一个数量级的,习惯用哪个就用哪个呗。

对了,许多人提起drupal,都会说白宫的网站就是drupal做的,其实白宫的访问量连drupal的官网都远比不上,而最牛的drupal站点当属examiner.com,alexa排名一千以内。而yii呢?据说19楼就是基于它开发的,也不错。
