HomeBackend DevelopmentPHP Tutorial为什么在本地测试ajax反应很慢

在本地测试ajax接收分页数据 要反应1s左右(以上) 但是放到服务器上就100ms到 900多ms之间 有什么好的办法解决ajax获取速度慢吗 已经把分页数据换成json了 没多大改善
数据大小显示是在2.9kb 耗时1.03s 处理逻辑就是简单查询了一下mysql的10条信息 字段也就3个

又测试了一下 返回一个很小的 392b的数据 还是返回在1s左右 应该是我本地数据库查询慢的问题了吗?

用的是jquery加ajax

这个问题很可能是你的本地是支持IPv6,并且你本地的Mysql支持反向解析惹的祸。
问题的解决办法有三种:

  1. 修改本地连接数据库localhost改为127.0.0.1,这是最简单的办法。

  2. 注册表禁用IPv6

  3. MySql禁用反向解析。

这里有篇博客可以参考一下:http://blog.onephp.net/archives/32/

需要先看看慢在了哪里。从数据上看似乎还是后台处理逻辑耗时长,这个就要看实现的逻辑怎么调优了。另外建议用chrome的开发者工具看看request各段的响应时间,再诊断一下是不是和网络有关。

@lovnie 问问题是需要技巧的,一个简单的办法是自问自答。
问:ajax请求本地慢,服务器快,是哪里导致的?
答:本地不太可能是网络问题,那就是后台接口慢咯!(那就debug调试看看接口响应时间啦)
问:接口哪里慢?(假设之前的分析是对的)
答:加上日志,分析耗时代码在哪里
然后这个问题就变成了XXX代码运行的为什么这么慢,再搜索一把,自己分析一下,解决不了再来提问,这样问题显得高级多了

Dependency Injection in PHP: Code Examples for BeginnersDependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

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.

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

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

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),
