Codeigniter基准测试，这些ms来自何处? [英] Codeigniter benchmarking, where are these ms coming from?

问题描述

我正在对网站进行基准测试.

I'm in the process of benchmarking my website.

class Home extends Controller {

    function Home() 
    {
        parent::Controller();
        $this->benchmark->mark('Constructor_start');

        $this->output->enable_profiler(TRUE);
        $this->load->library ('MasterPage');

        $this->benchmark->mark('Constructor_end');
    }

    function index() 
    {
        $this->benchmark->mark('Index_start');

        $this->masterpage->setMasterPage('master/home');
        $this->masterpage->addContent('home/index', 'page');
        $this->masterpage->show();

        $this->benchmark->mark('Index_end');
    }
}

这些是结果:

加载时基类:0.0076
构造函数:0.0007
索引:0.0440
控制器执行时间(首页/索引):0.4467
总执行时间:0.4545`

Loading Time Base Classes: 0.0076
Constructor: 0.0007
Index: 0.0440
Controller Execution Time ( Home/ Index ): 0.4467
Total Execution Time: 0.4545`

我了解以下内容:

• 加载时基类(0.0076)
• 构造函数(0.0007)
• 索引(0.0440)

但是其余时间是哪里来的?

推荐答案

我尚未对基于CI的网站进行很多基准测试，但0.4545的速度似乎并不快.

I haven't done a lot of benchmarking of CI-powered sites, but 0.4545 doesn't seem very fast.

在控制器执行时间(但不在您定义的基准测试范围内)下发生的一件事是自动加载config/autoload.php文件中定义的所有内容.如果您要在其中加载大量库或模型，那么这会增加控制器执行时间，而没有任何显而易见的原因.

One thing that occurs under the umbrella of Controller Execution Time (but outside your custom defined benchmarks) is the autoloading of everything defined in the config/autoload.php file. If you're loading numerous libraries or models there, that would add to your Controller Execution Time without any immediately obvious reason.
