1.4. Yaf的性能

对比

为了极限的看出Yaf框架的性能如何, 作者并没有和其他框架做对比, 而是和原生的PHP做对比, 测试代码如下:

例 1.1. 1.测试用原生的PHPorig.php

                                         
<?php
class IndexController {
        public function actionIndex() {
                echo "Laruence";
        }       
}

$controller = new IndexController();
$controller->actionIndex();
?>

例 1.2. 2.测试用的Yaf的入口文件ap.php

                                         
<?php
$conf = array(
        "application.directory" => "/home/laruence/local/www/htdocs/ap",
);

$app = new Yaf_Application($conf);
$app->run();

例 1.3. 2.测试用的Yaf的默认控制器Index.php

                                         
<?php
class IndexController extends Yaf_Controller {
        public function actionIndex() {
                $this->disableView(); //关闭视图输出
                echo "Laruence";
        }
}
?>

测试结果

作者简单的采用了ab作为测试工具, 分别在并发1, 100, 200的情况下对俩者做了测试.

说明

在测试的过程中, 通过vmstat观察, 机器的Idel一直保持在50-60左右.

总体来看, Yaf的性能比起原生的PHP, 损失的程度在10%左右, 另外考虑到因为Yaf有一次IO操作(载入Controller), 而原生的PHP并没有, 那么基本可以认为使用了Yaf框架以后, 性能损失在10%以内.

1.4. Yaf的性能 重要
在测试的过程中, 并没有多次挑选最好的数据来把测试结果弄的漂亮点. 因为有一些时候, Yaf的性能几乎和原生的PHP的性能差别在2%以内.

最后, 要说明一点: 测试结果, 只是一个简单的说明, 并不是为了证明什么结论. 因为框架的时间和真正应用逻辑的耗时比起来, 真的是很小的一部分.
