框架基准测试
=================

在过去，开发的web应用程序，性能问题并不是作为首要考虑的问题之一。因为硬件可以填补这方面的不足。然后，当Google决定把网站的速度作为搜索排名的条件之一时，性能的重要性就体现出来了。

以下的基准测试，将展示Phalcon和其他传统的PHP框架的性能对比，这些基准框架的版本都是最新的稳定版本。

我们欢迎程序员利用我们的基准测试程序进行测试，如果您有更好的优化方案或意见，请 `write us`_. `Check out source at Github`_

测试的环境?
-------------------
所有的框架都开启了 APC_ 缓存，且禁用了apache mod_rewrite模块，以避免产生额外的性能开销.

下面是测试的硬件环境:

* Operating System: Mac OS X Lion 10.7.4
* Web Server: Apache httpd 2.2.22
* PHP: 5.3.15
* CPU: 2.04 Ghz Intel Core i5
* Main Memory: 4GB 1333 MHz DDR3
* Hard Drive: 500GB SATA Disk

*PHP version and info:*
