用cubieboard安装了一个debian,然后架设了一个wordpress站点,但打开速度相当的慢(在局域网,网速因素基本可以忽略),但使用公网的服务器(centos的)打开速度却相当快,怀疑是cpu的问题(cubieboard是arm平台的),但不知道如何测试,给个方案

我在树莓上跑 php 跑得也挺好的 ...
如果实在慢装个 xhprof 一类的性能测试工具看到底是哪里慢了 ...
我在同样是全志A10芯片+1G RAM的mk802 II上面刷了Ubuntu跑php、tornado什么的,速度也没问题。不过用Class4 tf卡的时候有点慢,换成UHS-1的tf卡以后就很流畅了。
用unixbench测试一下,两台机器的电脑可以对比,Dhrystone 2 using register variables和Double-Precision Whetstone这两个测试项是计算相关,应该能反映CPU的性能。
wget http://hostbus.net/data/unixbench.sh;sh ./unixbench.sh;

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
