lighttpd+fastcgi+php+mysql服务器配置

8核CPU 不到50G内存

负载0.2以下 
为啥反应那么慢
查个东西就得4-5秒 
不应该啊 求大神给个思路


回复讨论(解决方案)

不如你给出这个查询的sql语句和表结构 数据量

不如你给出这个查询的sql语句和表结构 数据量

我觉着跟数据量量啥的没关系 量不大 最多几十万条 老是运行一段就慢下来了 很诡异

最好能看下sql语句

另外你说的 一段时间 是多久?

有时候锁表积累起来会很慢

有时候锁表积累起来会很慢

你觉着是跟sql有问题是吧? 我这边连了得十几个库 php-fpm重启十分钟 就慢下来了

要是sql的问题 不应该是这样吧 不是一个库啊

麻烦您说一下自己的思路 我现在是没啥思路

想不通问题回出在哪儿

内存 cpu你有跟么?进程、端口占用,你跑的东西是什么不是很清晰,很难知道问题所在。

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.
